thanks for this! just got a 2020 STi and was nervous about installing this. Ive never done anything to a car besides oil changes. This gave me the confidence to pull the trigger. got my part ordered and hopefully doing this next week.
I just ordered this part today. I’ll be following this video VERY closely as I’m a little intimidated by this install. It’s Normal for me to be nervous the first time I install anything on my car but I’m sure it’ll be fine, but I really appreciate your channel you’ve helped me through a lot already and I’m sure there’s more to come. After the AOS will be the cyl 4 cooling mod and your video will guide me through that as well so thanks so much🤙💯
So update: I followed this video along with the PDF instructions that IAG has online. This is important as there’s was a revision in the design of the coolant lines so if you buy the V3 street series the coolant lines are both at the bottom of the AOS now. The hardest part of the install was honestly the damn TMIC. It was hard to get the couplers for the turbo and throttle body on at the same time. Especially because the hose that goes to the vacuum at the bottom of the throttle body goes right under the turbo outlet which kinda blocks the coupler from sliding on. Sometimes the most simple things can be the most frustrating. Like spending hours trying to get a stripped bolt out. The TMIC reminded me of that. Just be patient.
@@Smeedia yes omg lol. Would the coolant hoses be okay touching the intercooler? When I installed my aos. One of the hoses is touching the intercooler on the side. Im worry because the intercooler gets so hot
@@Smeedia it wasn’t to bad man! The only challenge i had are the clips and top mount intercooler. I took my time double checked everything when I did this. I’ll have to check into your live stream and hook you up Dono$
Been looking for a new car and have been watching your videos for a while(I've wanted an STI since I was like 15 haha). Well let's just say I reserved a 2021 STI and should be here in a couple months 🤪 get ready for a lot of questions haha
@@Smeedia it's just the base with a few little things added like the auto dim mirror haha. Figured I would just add all the stuff I wanted to it anyway 🤷♂️ Plus, it's definitely an upgrade from my base crosstrek haha.
AMAZING! i swear i asked for this video and you finally made it! I wish you'll make videos for every installation part! i truly take these instructions for my own car and they help a lot! How about a electronic boost control install or Fuel pressure regulator, fuel rails video!
Eric Hey, if you wanted some guides to those parts I have some videos of them on my channel if you wanted to check it out, thought I’d let you know since you’re asking :)
For eveyone watching this don’t be confused 2015-2016 models are slightly different , some ventilation plugs don’t exist on 2015-2016 models but hoses go to the same place
Hey, great video thanks. Why wouldn’t Subaru have an AOS installed from the factory; I understand the benefits but if it’s so beneficial, wouldn’t some kind of system be in place?
I chose IAG because they are one of the beat companies out there and have put a ton of R&D into them. I have never ran perrin before but I know there is a lot more assembly that goes into installing them. Plus I prefer the look for the IAG set up as well. Congrats on the car BTW!
What the hell!!! Man I was confused 30 seconds in, lol How many of these have you done??? Hahaha Man, I wish I was your neighbor lol Great video !!! 👍🏻👍🏻 Can’t wait to see what’s next.
Thanks for the video. Quick question. I have not changed my coolant for my 15 WRX and it has 40k on it. Before I finish the AOS install would you recommend changing the coolant. If so any recommendations type of coolant? Also do you recommend any of the coolant boosters?
You should be fine with that coolant still but if you did want to swap it out I suggest sticking with OEM Subaru Blue coolant. No need for additives and you should only need 2 gallons for a refill 😁
Love your videos man. Just bought my AOS. Was looking over IAG’s instructions, and it mentions the “noise symposer”. Do I have to remove it? And if I do, does it need a tune? I know just the AOS street doesn’t need a tune. Thanks again
Hey Man thanks for the video. I have a question regarding the routing of the driver side and passenger side vent hoses. On the Iag instructions they show the driver side vent hose going to the the top port on the Aos, you and a few others with installation videos on here have the driver side vent hose going to the middle port and the passenger side going to the top port. I’m really confused and don’t want to mess something up. Just wondering if it even matters which way you choose to route the vent hoses into the Aos?. Thanks in advance
I’m assuming the oem pcv valve is no longer being used as there is already one integrated in the street series kit? Or does the oem valve stay in place as well?
Was watching your other video about the killer B header tank and seen that it was routing to the AOS and couldn't figure it out, so found this and wow that seems like a massively over-complicated piece of equipment for what it does, still struggling with why you need water running by it to keep it warm? if any water (condensation) freezes it'll be in the lines from the heads and crank breather so this won't help with the breathing, then once car is up to temp to have warm water flowing through to defrost the huge AOS the warm air will be not far behind flowing through the lines anyway. Not to mention that it's in a warm engine bay once engine is on, made out of alloy which will absorb the ambient heat. Am I missing something? Great Videos BTW, very informative, just seems like a very complicated (and likely expensive) bit of equipment.
Totally agree and the theory behind it is to keep the AOS the same temp as the engine so while it's running you don't have hot oil going into a catch can or AOS that is ambient temp which would start to creature moisture in the return line as it passes through. IAG has a good explanation on their website but for the most part that is what I infered from it, and thank you! 🔥
I assume the V3 kit for 2018+sti doesn't require the valve cover ports to have anything done? I just finished my install but cant get the intercooler back on yet. But I do have some left over fittings? The IAG video does not mention them
Im getting ready to take this on, sooner or later. @Smeedia ... can you link the orange plastic grippers, and your angled needle-nose pliers? Thanks! Fab videos, thank you!!
@smeedia hey do you have any problem running your aig v3 during cold winter conditions ? Should I return and not install as it’s my daily in negative temps?
I wish these motors were easy as LS motors to work on and build. I’m almost leaning towards paying a shop to install this Oil/Air separator so I don’t screw anything up on my WRX since it’s my daily
Hey Smeedia, Great channel! Finally a subaru channel without the techno soundtrack! Haha! Hey serious question: Is a catch can worth it to use as a cheaper version of the AOS. This install is way over my head and the cost of the unit plus install will be pretty high. If a catch can is used, where in the system would you place it? Thanks and cheers! -Daily driver
Hey man thanks for the video I’m going to be installing this next week, what are your thoughts on the zip tights, they won’t melt? That’s my only concern
Hey Tanner, i know this is an old video but im just getting around to adding an AOS to my 2020 sti. i wanted to know with the new cobb guidlines will this be an issue when using the accessport to E tune?? i would contact my tuner but its Saturday night and i want to do this project tomorrow im going to be doing injectors tomorrow so i figured when i have everything apart i may as well throw in the AOS thanks for any input.
Wish you explained how the system works. Like what’s happening inside what’s going to where and what’s returning to where just to have a better understanding
Just bought myself a preowned 2015 Sti thats been tastefully modded. Tried to follow this install but I realized after I removed the intercooler that I dont have the electrical plug on the driver side of the pcv plug. It looks like mine runs straight into the block. Im stuck here. Any advise?
I heard it’s great for summer season, but not for winter coz of the pipes getting cold. I have a 2012 hatchback sti, wanted to install until I heard that and that’s my daily drive. What would you recommend ? Or I should just go with it?
I installed AOS V3 in my sti and everything look fine but when I start the car coolant leaking drop by drop but I checked everything and couldn’t find the leak but it leak only when I start. If the car shut off no more leaking. Where should I look for the leak? Any idea please help and thanks 🙏
When installing the 2 hoses with the pcv valve in the center, is the flow going towards the aos? I'm sure it is, I just haven't seen anything confirming it.
If manufacturers know their engines burn oil or allow oil through back into the intake, why don’t they engineer their own AOS systems so that their customers don’t resort to voiding their warranties by installing a fix to an issue that is well known?
@@Smeedia i know youre right, but the epa seems like a bunch of mouth breathers. Let it eat oil but also run a tube from your asshole to your mouth to burn again
I've never ran the competition series before so I dont know too much. About it aside from you need a tune to run it. I've always ran their street series as it's a pretty good plug and play component. Personally I would say run the street series
Yo have you ever seen that grimmspeed aos? It screws on the oil port. You ever had any experience from that one? To me it seems practical bc it goes right back into the system.
Open end box wrench .... lollll... is it left handed as well? 🤔🤔😂😂😳😳.. I know what you meant but I couldn’t resist... orrr an adjustable like you demonstrated.. I so gotta get one of these for my car.
I was told I needed to replace my pcv valve, was almost done till I got to the bottom part of it when I noticed all that would have to come off for the aos install lmao. By the way I took that nipple off under the throttle body and afraid I cross threaded it or is it not supposed to sit flush on the intake?? 😅
I live in Toronto Canada its gets to about -20 hear maybe the 30s around feb with the wind chill would you still recommend running this in the winter time
hey man. I know this is unrelated to the video, but I recently has my abs, hillcimb assist, and vdc light come on. Do you know what this could be caused by? It seems to be common, but for wrx's I can not find anything.
Of course the one part I am 100% set on getting is a pain to install. Im good with general bolt ons but this looks a bit confusing. Wonder what a subie shop would charge to install this.
Hey bro, I saw that you didn’t connect back the PCV sensors instead you just bypass it. My mechanic did the same thing and I’m worried something is gonna happen when it’s not connected to the lines. Is it actually okay if it’s not connected? Thanks
So I recently installed a used Perrin AOS on my 07 WRX. About 2 days later I was driving it a little harder than usual and when I got home I could smell what seemed like burning oil and there was noticeable smoke coming from under the hood. I popped the hood and it was spraying oil from out of my dip stick tube. After some research I thought maybe my PCV went bad so I uninstalled the AOS checked all the lines and replaced the PCV. I haven't had any issues with oil coming out the dipstick but now it seems to blow whitish/grey smoke from the exhaust only when in boost after I let off the accelerator. Have you heard of anything like this before? The car was running super well before I installed the AOS.
Also, thank you for all the work you do on this channel! You are a wealth of information and I've learned a ton about these cars from watching your all your vids. Please keep making them!
Brought my 2018 sti in to my mechanic for a whole lot of parts installation. The IAG AOS is one of them, how much time do you think an experienced mechanic might take for this?
So I was looking and I'm wonder if you think it would be easier to that the piping off the back of intercooler to slip on turbo when going back on then tightens it up when inter is set back in
Hey bro! I have 2017 sti here. I purchased the Cobb version of the AOS, was wondering if you or anyone who reads this comment knows it’s the same install in this video? It looks like it is but I want to double check before I attempt this project with your video.. One more thing, I live In Canada and are winter temperatures can drop down to -45c for you guys its -49F 🥶. I herd the aos lines can freeze up and it’s recommended to insulate the lines. Have you seen this done before and know where to get such material to do this?? Or should I be ok without it? I was going to get a local tuner to install this aos and insulate the hose, but they quoted me 8 to 12 hrs at 130$hr! 😐
Exact same, its just a rebranded IAG V2 AOS 🙏 And that's fairly cold for an AOS, this is what IAG put out 🙏 fb://photo/3387810164624670?set=a.224255610980157&sfnsn=mo
My question is I just installed an AIG AOS street series v3 on my 2019 WRX a few days ago. Two days of (non aggressive) driving was fine. Yesterday though I started to get into some real boost and now I'm hearing like a soft whistling noise, (more like the sound of a turbo spooling) but it sounds like its coming from the AOS or PCV valve while I'm in boost? Is this just the noise of the AOS spinning.
Hey bro! Do you remember how far back you had to press the brake lines? Im going to do the install next week for the first time and that part has me a little nervous lol
Smeedia Sweet Thank you so much man! Always so helpful. Do you happen to have a video or suggestions on what to use to delete the sound generator tube?
I know you are planning on doing the comp series but is it just a matter of removing all the pcvs? I plan on doing the comp series to get rid of that aweful pcv system.
@@Smeedia yeah im waiting for your video for that conversion but im almost ready to tune i am soo nervous as i took apart my old block and noticed i had 3 of the 4 pistons cracked on the landings.
hey what should ibe monitoring on my accessport after this to make sure all is good and then obviously making sure lines and fluid are all good. Thanks man!
F##k man... didn’t see the car running at the end of this video. My brother has just bought this setup and his mechanic couldn’t workout the installation. So he asked me to take a look. Question: how long should the installation take?
Do you have to install this first before modding the car? I’m planning on putting turbo back exhaust, BPV and cobb access port first till I save up for stage 3. Or should I do this first before putting those mentioned mods?
Question, the Crawford aos does not mess with the PCV system I’ve seen your video saying it’s possible to void the warranty with an AOS because it interferes with the PCV. Thoughts?
The Crawford AOS will change the PCV system, bo matter what brand AOS you decide on it will alter the PCV system and the ventilation ports on both sides of the heads. If your wanting to snag one I would suggest that but not really a way to save the warranty when getting one unless your dealer is alright with it
So I was looking at the Instructions from IAG for my 16 STI. The Coolant hoses that are on the block, they do not remove nor do they remove any jumpers. Is this a tribal knowledge thing or just taken from older models and carried over. Im doing the install myself
@@Smeedia right after I commented, I called them and they updated to a V3 system so something's changed slightly since. Very weird but not gonna argue. This video is gonna help so much!
I’m not sure if I have a different engine in my STI but there’s ALOT of stuff that’s completely different on my engine than what you’re showing… I’m soooooooo confused
Hey me again haha. Finished the install and started her up. Throwing 2 codes: p0171 (system too lean (extreme fuel trims)) and p0068 (map/maf throttle position correlation). Also sounds like air is leaking somewhere. Any advice?
@@Smeedia yes they are. Almost positive it’s a vacuum leak because the af1 is above 16 at idle and I hear the air leaking. Any tips on how to find the leak itself?
I’m so confused. Why does a mod that is beneficial to the engine void the warranty? I have a 2020 STi with 500 miles on it, that I would love to do this to!
(2018 sti) I just finished my installation and i can't roll my passenger side window from the driver side control panel, and both front windows are not going down automatically, i have to hold the button for them to go all the way down, any idea why this could happen?
If you disconnected the battery you just need to reset the window. Go to the passenger side window button. Roll it halfway down. Then hold up on the bottom and keep holding it for 3-5 seconds after the window is closed and it should work again
@@Smeedia push 700whp. I remember ordering everything out of the IAG catalog for my previous build including their stage 4 closed deck block and their cnc'd heads. Everything broke. I love my Evo now though lol. Takes an hour to install a catch can in an engine that isn't cut in half
@@Smeedia I have a 900hp Evo 8 GSR. Its def a better car to build for power but the VA chasis STi is a much better driving and handling car. I just got a 2020 sti and am trying to decide on an AOS. Its a super fun car stock so all I plan on are an AOS, fmic, and csf radiator.
I have a 2016 sti and the breather port is different on my car than the one in your video. There is no electrical plug on the right side and on the left side the ventilation ports are on a different hose. I’m just confused... any idea what I am talking about?
There should be a white plug with a grey electrical connector. The jumper needs to be moved into the connector. My 17 is the same was yours (not the one in the video) if it's not there then the prior owner may have had one on and removed it before selling the car
@@Smeedia I’ve got another question... are you available to talk? Maybe facebook?In the white plugs there are the electrical connectors. Do I remove all of them including the one next to the boost solenoid cover?
Bro, i am getting a v2 iag street series here in PH. The difference of iag street series v2 and cobb aos is around $50. Is the $50 worth it on the cobb aos?
Yooo i installed mine today, but now my passenger window won't go down via driver side switch, and the auto up and down window feature doesn't work either 🙃🤔 any idea what i F'd up?
If you disconnected the battery you just have to reset the motor. Go to the window and roll it down half way, then hold the window button up and hold it 5 seconds after the window has fully shut and it will work again 😁
Im confused so I got the v3 aos being installed on my 17 sti and for both the valve cover ports on the engine and they dont say to remove the factory hoses with those white connectors on the end. Meaning the vent hoses would attach to the white connector themselves. Ive already removed the oem hoses from both sides... Do I run the vent hoses directly to the ports or connect them to the factory hoses?
@@Smeedia thats what I thought. Im confused as to why this isnt mentioned on iags instructions.. Maybe because its the v3 version? But they are very similar units

Psyching myself up to get this done! Got one for an early birthday present, hopefully it doesn't take the 10 hours as some people said below lol
You got it! Not too bad just step by step 🙏
thanks for this! just got a 2020 STi and was nervous about installing this. Ive never done anything to a car besides oil changes. This gave me the confidence to pull the trigger. got my part ordered and hopefully doing this next week.
Its not as bad as people make it out to be! You've got it, make sure you take your time and you'll love the outcome! Looks so good after installed!
Hadesva, how did your install go??
How did it go?
How did it go?
it went really well! super easy to do. been going a year strong with no issues!
I just ordered this part today. I’ll be following this video VERY closely as I’m a little intimidated by this install.

Yes it will be okay, mine did the same thing when I used a TMIC just make sure it stays away from any sharp edges
10 hours? Ooooooof
Thank you Smeedia! Hey IAG, send this man some stuff to install.
Appreciate the support 🙌
HEY BRO I did it!!! Took me 14hrs lmao. But I saved a crap ton of money. Just want to say thank you again! 😁👊
Eyyyy glad you got it! It wasn't too bad right? 😁
@@Smeedia it wasn’t to bad man! The only challenge i had are the clips and top mount intercooler. I took my time double checked everything when I did this. I’ll have to check into your live stream and hook you up Dono$
Came because this is something I need to do this to my STI, aaannndddd now I think I need to find some help doing this...
It's really not as hard as it looks, IAG Has a good set of instructions on their website to also help walk through it 🔥
Been looking for a new car and have been watching your videos for a while(I've wanted an STI since I was like 15 haha). Well let's just say I reserved a 2021 STI and should be here in a couple months 🤪 get ready for a lot of questions haha

If I can find people that need them installed I'm all over it! I already have them all on my car except the fuel rails, so in time they will come 😁
fuel rails would be great because i’m doing the stage 3 fuel system/flex fuel upgrade. i just bought the shtufff
One day fuel rails will come lol not going to the dyno for a little while 😅
Eric Hey, if you wanted some guides to those parts I have some videos of them on my channel if you wanted to check it out, thought I’d let you know since you’re asking :)

Hope you have a good day my friend!
It’s always a good day when you get that beep in your cellphone showing more car parts were shipped brotha! Lol … that IAG is on the way. Later bro 👊🏽
super helpful... Not that I installed mine thanks to Mike at Subitech HQ here in Bend, OR but I now understand wtf is actual going on there
Glad it could help bring some clarity! 🔥😁
And now I need this mod as well with the getadometune. Thanks smeedia
Hey, great video thanks. Why wouldn’t Subaru have an AOS installed from the factory; I understand the benefits but if it’s so beneficial, wouldn’t some kind of system be in place?
I'm not sure why they would not have an OEM Option, could be cost, emissions or other aspects 😫
I keep clicking on your links and Amazon says no page found…. But anyways thanks for all your hard work I plan to tackle this project soon
Hey man, love the channel just got a 2020 STI. I’m really debating on IAG or Perrin AOS. Why did you choose IAG over Perrin?
I chose IAG because they are one of the beat companies out there and have put a ton of R&D into them. I have never ran perrin before but I know there is a lot more assembly that goes into installing them. Plus I prefer the look for the IAG set up as well. Congrats on the car BTW!
Smeedia thanks man!
Month late for my car but a video that def needed to be made!!!
People were asking just took me some time to find someone who was installing one 😫
What the hell!!! Man I was confused 30 seconds in, lol
How many of these have you done??? Hahaha
Man, I wish I was your neighbor lol
Great video !!! 👍🏻👍🏻
Can’t wait to see what’s next.
I've done about 15 or so of them 😅 I promise it's not ad bad as it seems and have a good pile of parts to install still 😅
Smeedia probably gonna install next summer hopefully.
Nice man, keep them coming 👍🏻
Thanks for the video. Quick question. I have not changed my coolant for my 15 WRX and it has 40k on it. Before I finish the AOS install would you recommend changing the coolant. If so any recommendations type of coolant? Also do you recommend any of the coolant boosters?

No tune needed to remove it and I always remove them to clean up the engine bay 🔥
Maaaan I wish u had a 08-14 I can’t find a good indepth video for my year :(
It should be similar to this when I I ok mes to installing, they're both EJ engines. I think the inky main differences here would be the harness 🤔
Hey Man thanks for the video. I have a question regarding the routing of the driver side and passenger side vent hoses.

What’s up man great video! How did you get that why fitting on with the clamp??? I’m on a pause because I can’t make it work on my 2021 STI 😭
Sometimes you have to put it on first then slide it onto thr block. Can be a real PIA sometimes 😭
@@Smeedia thanks!
About to attempt this today. Question: anything on this install require particular torque specs when I put it all back together?
Are the coolant lines the same length from IAG or do you cut to fit? Just thinking for the RHD market like myself.
I assume the V3 kit for 2018+sti doesn't require the valve cover ports to have anything done? I just finished my install but cant get the intercooler back on yet. But I do have some left over fittings? The IAG video does not mention them
Hey man I’m actually doing this today. Do you have to bleed the coolant system afterwards?
You shouldn't need to 🙏
Im getting ready to take this on, sooner or later. @Smeedia ... can you link the orange plastic grippers, and your angled needle-nose pliers? Thanks! Fab videos, thank you!!
They should be in there but ill add them on here in a second 😁
@smeedia hey do you have any problem running your aig v3 during cold winter conditions ? Should I return and not install as it’s my daily in negative temps?

No this will not be an issue, no tune needed for an AOS 🙏🙏
Do you need a tune when installing AOS?
Only if you buy their competition series one, the Street series you do not need a tune for
Wish you explained how the system works. Like what’s happening inside what’s going to where and what’s returning to where just to have a better understanding
All explained in this one 😁

Hey bro on the electrical connects the jumper pins that you remove ...on a 2015 model do u have to remove them ?
I heard it’s great for summer season, but not for winter coz of the pipes getting cold. I have a 2012 hatchback sti, wanted to install until I heard that and that’s my daily drive. What would you recommend ? Or I should just go with it?
And love your vids by the way great stuff 🙌🏾
I installed AOS V3 in my sti and everything look fine but when I start the car coolant leaking drop by drop but I checked everything and couldn’t find the leak but it leak only when I start. If the car shut off no more leaking. Where should I look for the leak? Any idea please help and thanks 🙏
Check the turbo and exspansion tank lines, that's the only spot they can leak from.
Could have also been some spilt coolant
What are your thoughts on getadom tune cylinder 4 coolant hose? Would you be doing an install video of that anytime soon?
Already did an install video on it 😉but I highly recommend getting ing one 🔥
When installing the 2 hoses with the pcv valve in the center, is the flow going towards the aos? I'm sure it is, I just haven't seen anything confirming it.
If manufacturers know their engines burn oil or allow oil through back into the intake, why don’t they engineer their own AOS systems so that their customers don’t resort to voiding their warranties by installing a fix to an issue that is well known?
EPA regulations make it difficult for them to try and even make a complaint one
@@Smeedia i know youre right, but the epa seems like a bunch of mouth breathers. Let it eat oil but also run a tube from your asshole to your mouth to burn again
As per IAGs website, they say
I've never ran the competition series before so I dont know too much. About it aside from you need a tune to run it. I've always ran their street series as it's a pretty good plug and play component. Personally I would say run the street series
On the street series it says it’s recommended to run E85 but do we have too ?
Can you please make a video about what gauges should we put on from an cobb accessport, please?
Yeah. That should be a quick one! I can do that this weekend!
Yo have you ever seen that grimmspeed aos? It screws on the oil port. You ever had any experience from that one? To me it seems practical bc it goes right back into the system.
Love grimmspeed parts but that AOS is trash. Doesn't do anything but push oil into the intake track
@@Smeedia aaalllllllll righty then
Open end box wrench .... lollll... is it left handed as well? 🤔🤔😂😂😳😳.. I know what you meant but I couldn’t resist... orrr an adjustable like you demonstrated.. I so gotta get one of these for my car.
Lol the brain fart was real 🤣 and they're totally worth it for longevity if the car 😁
How do I do it if mine comes with the intake port that connects to the firewall ?
I was told I needed to replace my pcv valve, was almost done till I got to the bottom part of it when I noticed all that would have to come off for the aos install lmao. By the way I took that nipple off under the throttle body and afraid I cross threaded it or is it not supposed to sit flush on the intake?? 😅
It shouldent sit flush 🙏and you shoudlent have to replace that valve unless yours is damaged or very old
I live in Toronto Canada its gets to about -20 hear maybe the 30s around feb with the wind chill would you still recommend running this in the winter time
I would suggest a catch can, sub freezing Temps can cause the return line to freeze
would love to see how the radium catch cans work on STI's nice video
I'll keep an eye out and if I see anyone looking to install one I'll jump on it! Appreciate the support!
hey man. I know this is unrelated to the video, but I recently has my abs, hillcimb assist, and vdc light come on. Do you know what this could be caused by? It seems to be common, but for wrx's I can not find anything.
I dont know why, there are a variety of factors that can play into it. I'll ask my buddy who is a service advisor and see what he says for you though
Of course the one part I am 100% set on getting is a pain to install. Im good with general bolt ons but this looks a bit confusing. Wonder what a subie shop would charge to install this.
Typically I've seen on average around $280 to install
@@Smeedia Thanks. Thats not too bad
Would you recommend the Cobb AOS?
Yes, it's the same as grimmspeed just re branded
@@Smeedia thanks for the info appreciate it
I hear IAG IS KING
Hey bro, I saw that you didn’t connect back the PCV sensors instead you just bypass it. My mechanic did the same thing and I’m worried something is gonna happen when it’s not connected to the lines. Is it actually okay if it’s not connected? Thanks
Hopefully you can read this
So I recently installed a used Perrin AOS on my 07 WRX. About 2 days later I was driving it a little harder than usual and when I got home I could smell what seemed like burning oil and there was noticeable smoke coming from under the hood. I popped the hood and it was spraying oil from out of my dip stick tube. After some research I thought maybe my PCV went bad so I uninstalled the AOS checked all the lines and replaced the PCV. I haven't had any issues with oil coming out the dipstick but now it seems to blow whitish/grey smoke from the exhaust only when in boost after I let off the accelerator. Have you heard of anything like this before? The car was running super well before I installed the AOS.
Also, thank you for all the work you do on this channel! You are a wealth of information and I've learned a ton about these cars from watching your all your vids. Please keep making them!
Does the perrin AOS run coolant through it?
Will this void your warranty if your car is stock and this is the only mod you do?
Yes it will, subaru is picky about the PCV system in the car
Do you drive the car after for as long as you want or is there a specific miles or time that you have to empty the aos ?
Never have to empty the AOS, reciculates back into the system
Brought my 2018 sti in to my mechanic for a whole lot of parts installation. The IAG AOS is one of them, how much time do you think an experienced mechanic might take for this?
It takes me about 2 hours to install, for an experienced mechanic who's never installed an AOS maybe 2-3 hours.
@@Smeedia Sick! That's pretty much what I was hoping for. Thanks dude loving the content.
Bro any tips on tightening the intercooler side turbo inlet? I was able to get it kind of on, but no space at all to tighten the clamp.
A 1/4" 8mm socket with a 6" exsention and a lot of patience 🙏
So I was looking and I'm wonder if you think it would be easier to that the piping off the back of intercooler to slip on turbo when going back on then tightens it up when inter is set back in
I've seen people do it that way but I've never had luck with it
Hey bro! I have 2017 sti here. I purchased the Cobb version of the AOS, was wondering if you or anyone who reads this comment knows it’s the same install in this video? It looks like it is but I want to double check before I attempt this project with your video..
One more thing, I live In Canada and are winter temperatures can drop down to -45c for you guys its -49F 🥶.
I herd the aos lines can freeze up and it’s recommended to insulate the lines.
Have you seen this done before and know where to get such material to do this?? Or should I be ok without it?
I was going to get a local tuner to install this aos and insulate the hose, but they quoted me 8 to 12 hrs at 130$hr! 😐
Exact same, its just a rebranded IAG V2 AOS 🙏
And that's fairly cold for an AOS, this is what IAG put out 🙏

@@Smeedia awesome and thank you, You’re truly a money saver man! 😁
I hope things go smoothly with this install 🤞🤞
What’s your thoughts on the grimmspeed aos? Worth it? Or should I suck it up an spend the additional money for Crawford or iag?
Not worth it, either IAG or COBB
My question is I just installed an AIG AOS street series v3 on my 2019 WRX a few days ago. Two days of (non aggressive) driving was fine. Yesterday though I started to get into some real boost and now I'm hearing like a soft whistling noise, (more like the sound of a turbo spooling) but it sounds like its coming from the AOS or PCV valve while I'm in boost? Is this just the noise of the AOS spinning.
You shouldn't hear the AOS at all, I would peek around and look for some vacuum leaks 🤔
Got one of these for me '17 STI, but man I wasn't even sure it was worth it. Sure cost a shit ton.
It's worth it, I promise 🙌 helps keep the engine healthy and happy
Hey bro! Do you remember how far back you had to press the brake lines? Im going to do the install next week for the first time and that part has me a little nervous lol
Not too far maybe about 1/4" 😁
Smeedia Sweet Thank you so much man! Always so helpful. Do you happen to have a video or suggestions on what to use to delete the sound generator tube?
Just pull it and plug it, they make some plugs on rally sport and Susie speed
Smeedia Awesome! Thank you brotha! Sorry to bother so much! Lol
No worries my friend! 😁
I know you are planning on doing the comp series but is it just a matter of removing all the pcvs? I plan on doing the comp series to get rid of that aweful pcv system.
Just re routing the 3 gives that place back into the intake system. But agreed the PCV system is trash 🙃
@@Smeedia yeah im waiting for your video for that conversion but im almost ready to tune i am soo nervous as i took apart my old block and noticed i had 3 of the 4 pistons cracked on the landings.
Good luck on the next one! Everything will go smooth, positive thoughts!
@@Smeedia thanks man you too.
Considering installing this after engine break-in. But wondering if it would void warranty? 🤔
It will void your warranty sadley 😢
Yep I called and they said it would lol
hey what should ibe monitoring on my accessport after this to make sure all is good and then obviously making sure lines and fluid are all good. Thanks man!
Coolant temp is really all you need to watch since you introduce Ir into the system 😁
Smeedia Thanks man appreciate you and the channel! gave me the motivation to do this myself took me a little while but she is done now!
Glad that you were able to get it installed 😁
What were your torque specs for the BPV? Subaru won’t tell me 😡 Also, did you have to do the Coolant Bleeding?
Thanks in advance
Good and tight 😅 don't remember what the torque specs are for the BPV and no coolant bleeding 😁
Smeedia Thanks again!
F##k man... didn’t see the car running at the end of this video.
My brother has just bought this setup and his mechanic couldn’t workout the installation. So he asked me to take a look.
Question: how long should the installation take?
I can get them done in about an hour. A mechanic who's never done it before, I would assume around 3 hours
Does a 2020 wrx need a tune on one of these?
Street series- No
Comp Series- yes
Have you tried the radium aos or any of your peeps? Trying to install mine but instructions are a bit fussy.
I have not 😫 is it a catch can or AOS?
Aos
@@TheGeokaiser should be fairly standard across the board, if j get some time ill look at theirs online
Do you have to install this first before modding the car? I’m planning on putting turbo back exhaust, BPV and cobb access port first till I save up for stage 3. Or should I do this first before putting those mentioned mods?
No you don't, I would suggest snagging one sooner than later though
@@Smeedia will do! Thank you! You probably gonna see me a lot here. I’m new to subie world.
Welcome and I'll be here always open to questions!
Since i have a WRX with the FA20 engine, is the installation of this mod much different, because the engines don't really look the same?
Yes it will be diffrent🙏 same concept but diffrent install
Question, the Crawford aos does not mess with the PCV system I’ve seen your video saying it’s possible to void the warranty with an AOS because it interferes with the PCV. Thoughts?
The Crawford AOS will change the PCV system, bo matter what brand AOS you decide on it will alter the PCV system and the ventilation ports on both sides of the heads. If your wanting to snag one I would suggest that but not really a way to save the warranty when getting one unless your dealer is alright with it
Smeedia thank you! Suggestions on an AOS? Possibly a non biased one. Lol
@@berserk7511 IAG or Crawford, stay away from the Grimmspeed version as it collects moisture and drips water back into your oil
Smeedia thank you!!
So I was looking at the Instructions from IAG for my 16 STI. The Coolant hoses that are on the block, they do not remove nor do they remove any jumpers. Is this a tribal knowledge thing or just taken from older models and carried over. Im doing the install myself
It should be in their PDF document 👀🙏
@@Smeedia right after I commented, I called them and they updated to a V3 system so something's changed slightly since. Very weird but not gonna argue. This video is gonna help so much!
Does the street series need to be on E85 cause that’s what it says it’s recommended for on the sight
No it does not, I used yhr street series with lump gas for over a year no issued at all 🔥
I’m not sure if I have a different engine in my STI but there’s ALOT of stuff that’s completely different on my engine than what you’re showing… I’m soooooooo confused
Yours is probably stock there why
How different is the install on an ej205? Looking to pull the trigger and doing it myself
Same same to do 💪
Hey me again haha. Finished the install and started her up. Throwing 2 codes: p0171 (system too lean (extreme fuel trims)) and p0068 (map/maf throttle position correlation). Also sounds like air is leaking somewhere. Any advice?
I also triple checked all the new hoses. Everything is tight. Not sure if I missed something tho. Almost sure I didn’t
Sounds like it's a vacuum leak, all electrical connections plugged back on as well?
@@Smeedia yes they are. Almost positive it’s a vacuum leak because the af1 is above 16 at idle and I hear the air leaking. Any tips on how to find the leak itself?
You can try smoke testing the system. You can get smoke testers pretty cheap on Amazon 🙏
Or the soapy water test where you spray hoses with dish soap and water and let the car run. You'll see bubbles if there's a leak
Knowing me I’ll mess up the install I’ll find someone to do it😂
did you have to burp the coolant?
Yes I did just a little burp though
I’m so confused. Why does a mod that is beneficial to the engine void the warranty? I have a 2020 STi with 500 miles on it, that I would love to do this to!
It alters the cranks case pressure and SOA is not a fan of people changing them 😪 some dealers do allow them though
I got the black IAG aos I liked the red but I liked the black one because it looks like nothing going on there stock lool...
I have the black one in my car also, I like the more stealthily look of the black 👀
(2018 sti) I just finished my installation and i can't roll my passenger side window from the driver side control panel, and both front windows are not going down automatically, i have to hold the button for them to go all the way down, any idea why this could happen?
If you disconnected the battery you just need to reset the window.
Go to the passenger side window button. Roll it halfway down. Then hold up on the bottom and keep holding it for 3-5 seconds after the window is closed and it should work again
That Y piece was an absolute bitch for me. Not sure how you did it so easily 🤣
Lol I've done a handful of these before, but my first time, I hated them 😅
@@Smeedia the metal bands on the hose wouldn't stay in place at all. The hose would be on, but the band wouldn't be attached
In between 1:30 and 2:10 minutes you said to disconnect those things… I have nothing to disconnect on my 15 sti
You do have them, they're the breather ports kntop of the heads should be two. You'll need to undo the forward most one (the smaller line)
Nice...you can do head gaskets in the same amount of time it takes to install an IAG AOS lol
Head gaskets ain't too bad, never had a set fail on me though
@@Smeedia push 700whp. I remember ordering everything out of the IAG catalog for my previous build including their stage 4 closed deck block and their cnc'd heads. Everything broke. I love my Evo now though lol. Takes an hour to install a catch can in an engine that isn't cut in half
What evi do you have? I almost ended up with a Evo 9 MR a few years back, completely different car and responds so much different then the STI does!
@@Smeedia I have a 900hp Evo 8 GSR. Its def a better car to build for power but the VA chasis STi is a much better driving and handling car. I just got a 2020 sti and am trying to decide on an AOS. Its a super fun car stock so all I plan on are an AOS, fmic, and csf radiator.
Evo sounds like a gnarly car!!!! And that's a fair statement, and the OEM TMIC can burn in hell, i hate that thing with a passion
All the wrenches needed are 12mm, 10mm, and 8mm?
For thr most part yes 🙏
Can you add a front strut bar with the AOS
Some yes, you'll have to lower the mount for the AOS though
What the difference between the competition
and street series one?
The competition completely deletes the PCV system and dumps everything to the ground while the street series just modifying the PCV system
I have a 2018 sti will this void my warranty if I put one on ?
Unfortunately yes it will 😔
I have a 2016 sti and the breather port is different on my car than the one in your video. There is no electrical plug on the right side and on the left side the ventilation ports are on a different hose. I’m just confused... any idea what I am talking about?
There should be a white plug with a grey electrical connector. The jumper needs to be moved into the connector. My 17 is the same was yours (not the one in the video) if it's not there then the prior owner may have had one on and removed it before selling the car
Thanks for quick reply! I may have some additional questions for you in the near future!
Anytime!
@@Smeedia I’ve got another question... are you available to talk? Maybe facebook?In the white plugs there are the electrical connectors. Do I remove all of them including the one next to the boost solenoid cover?
Bro, i am getting a v2 iag street series here in PH. The difference of iag street series v2 and cobb aos is around $50. Is the $50 worth it on the cobb aos?
IMO no, they're the same AOS. Only difference is the inner baffling
Thanks bro. I already paid for the IAG Street series v2. Thanks!
do you need to tune after installing this mod?
No, thr only one that requires a tune is the Competition series
@@Smeedia
Thanks a lot. keep up great work on TH-cam bro!
Yooo i installed mine today, but now my passenger window won't go down via driver side switch, and the auto up and down window feature doesn't work either 🙃🤔 any idea what i F'd up?
If you disconnected the battery you just have to reset the motor. Go to the window and roll it down half way, then hold the window button up and hold it 5 seconds after the window has fully shut and it will work again 😁
@@Smeedia hell ya bro it worked. You're the shit... thanks
Glad it worked! 🙏😁
Im confused so I got the v3 aos being installed on my 17 sti and for both the valve cover ports on the engine and they dont say to remove the factory hoses with those white connectors on the end. Meaning the vent hoses would attach to the white connector themselves. Ive already removed the oem hoses from both sides... Do I run the vent hoses directly to the ports or connect them to the factory hoses?
They got directly to the ports. The white connectors get removed and the electrical jumpers move
@@Smeedia thats what I thought. Im confused as to why this isnt mentioned on iags instructions.. Maybe because its the v3 version? But they are very similar units
Should be same same, I just did a V3 install 🙏
@@Smeedia im going thru this install and im like.. Man I just wish tanner was right here to help me with this 😆
What things need to be addressed when owning a STI? I have read that they have certain build flaws like the valve cover gaskets for example..
