I installed the IAG AOS... first off let me tell you, love the system, easy to install. Second you will notice right away - I am running Stage 2+ oil smell and excessive white smoke. Perrin makes an item that they include in their system that all AOS systems should include to handle the turbo sump issue. Just a recommendation to get that part if anyone is installing this on their car.
for those not in the loop, an aos or catch can helps decrease carbon build up on intake valves for vehicles with direct injection. if you have a port injection motor the fuel injectors do a good job of cleaning intake valves with gas so this system isnt as important.
Pretty interesting. I had always thought the two terms were interchangeable. Didn't realize they were actually 2 separate products. Looking forward to seeing the upcoming install video.
I hope you do an install of the AOS detailed keeping in mind that people like myself have never worked on cars but like to learn and do it right. I’ve seen people install these but they speed thru it and not show actual details. Don’t show what hose was disconnected or how to find it, things of that nature. I’ve been quoted $600 to install, so yeah would love to do it myself! lol.
I bought this from subispeed a couple of years ago and installed on my car. The mechanic at subaru in GA was saying those are the same thing because it's still a can.
I’ve been using the grimmspeed AOS with Cusco catch can for 3 years, and luckily, no issues (oil froth) or oil found in the catch can. I do occasional spirited driving. I recently checked my tmic for oil residue, no oil, so it holds up well for normal driving. I believe the IAG is more for auto crossing.
Thank you! I got a AOS on my 08 STI and thought I had to maintain it like the catch can. But now I know thanks to you. Oh yeah and I just subscribed 👌🏽
SubiSpeed i would really appreciate it. the website some times takes like 15 seconds to load new pages. i know it’s not my internet because it’s the only website that does this and other people have the same issue. again, the website is just very slow loading pages. it’s been like this since forever. it makes browsing your website not enjoyable.
Would you recommend getting an AOS if you live in a cold climate and use Flex Fuel? I've heard that those 2 things can each cause sludge buildup in the lines which leads to them needing to be replaced every once in a while. My thought is if you have both of those at once doubling the buildup would it be worth it to even get one in the first place with how much you would have to replace the lines? Any info would be greatly appreciated. I don't own my WRX anymore, but I miss it so much I'm in the process of getting another one lol. Have always loved your guys vids!
Yes, an AOS is even more recommended if you're running flex. As for the cold climate, you just want to make sure to warm your car up properly as condensation may freeze in the lines.
Honestly we recommend not modifying your car if you are worried about your warranty. Even though a part may not directly void your warranty, your dealership may still give you a hard time if something were to come up.
Wouldnt either one of these systems (Catch Can or AOS) help vehicles with only Direct Injection a lot? I heard that's why a lot of VW guys run them and is the reason why I'm definitely looking for one for my 2018 Crosstrek. Just for longevity and peace of mind.
For the AOS, is this something that you'd peg as necessary right away or is it more something that you use as a vehicle ages? Like would you go slapping this on a brand new car or not so much?
I've just got a 2019 STI as well and my tuner highly recommends the installation of an AOS even on a brand new stock vehicle. It is a worthwhile investment.
@@SubiSpeed Okay that is fair. Does it have warranty implications or not really? From what I understand, it doesn't seem like it's something that could hurt anything...
Check your warranty agreement with Subaru or your local dealer. To answer your question, I would install an AOS ASAP if you typically drive the car hard, even if it was a new car. If you drive very conservatively and stay out of high boost then you will be fine without it for a while. Over time, if you check your intake component couplers you may notice oil starting to accumulate. Your throttle body or intercooler/piping could also show signs of condensed oil accumulating. It becomes more apparent with increased "blow-by" caused by high boost pressures, wear on piston rings' and cylinders' seal (tightness?), and prolonged operation in higher revs. Without the AOS or catch can, it is recommended that you clean any excess oil out of intake components as part of general engine maintenance. The AOS helps reduce the amount of oil vapor that would otherwise have made its way into the intake. As was mentioned in the video, excess oil vapor mixing back into the intake supply can lead to carbon deposits and lower effective octane level. What he didn't say is, risk of knock or pre-detonation increases with lower octane. Knock/pre-detonation is an explosion in the combustion chamber off timing, or when it's not supposed to. It causes destructive interference in the crank rotation and can lead to severe damage to vital engine components (think explosion but no where for the explosion to go, so cylinder pressures skyrocket until exhaust valves open). Avoid knock.
I had the Cusco catch can on my sti and it did not catch anything until my engine blew up (cyl4) and then it started to catch oil. I have upgraded to the IAG aos after the rebuild per recommendation and it SEEMS to work better ie, its catching blow-by.
If i have a 2014 WRX stage 3+ do i need a IAG "street" Air Oil Separator or a IAG "competition" Air Oil Separator. I'm running a reliable 400+ whp. I'm not competing
What is the Difference between the IAG AOS Street Series vs IAG AOS Comp Series? The Price change's So, What's the Difference and which one is Best? Been Contemplating on Getting the Street Series as everyone has them, but your COMP series is A bit cheaper and I want to know why and what's the Difference like for reals. I dont want to spend the money when they are the same thing and next thing you know Regreting that I should have went with the Street Series or the Comp Series.
The pin out for the 18+ models is different and requires new circuitry work on the headlights for them to be compatible so it might be a while before they're available.
Around what mileage should either of these mods be added to the car? Also is there an repercussions if you don’t race/track your car but still install these mods?
I'm very positive these void the warranty on vehicles. So I would only do this if you are very confident. But i would leave it, especially on a new 2020 with the warranty (im sure) still good.
If you want the most preventative measures, yes. Shouldn't cause any leaks as long as you go with a quality setup and assure all the fittings and lines are installed correctly.
When it comes to towing with the WRX or STI I would have to advise against it. These vehicles are not meant for towing. Even though some people may or may not have had success with towing small trailers and such I just wouldn't want to risk it. I recommend heeding the warning in the manual.

So I just bought a grimmspeed stealthbox intake and i just wanted to know how often and how exactly should I wash the filter itself. Love the intake btw.
Do you have to change the filter elements on the AOS? Wouldn't there be build up? Nothing on an engine is truly set it & forget it. Especially when it involves waste.
@@SubiSpeed I asked because it looked like some sort of filter element near the casing but I guess it's considered baffling. It still appeared like it could easily slide out for cleaning, can it? Thanks for your time. I'm really researching this whole catch can subject by comparing the various components involved within the cans. I also don't know if I am going to need a 3 port can? I also saw a Moroso vacuum pump catch can which seems to be the only brand making that specific can. I'm thinking that if you have any air pump like I do on my ML55 AMG that it would apply to that kind of system? Anyhow, so far it seems like I am down to UPR, RXPERFORMANCE which is almost impossible to find for sale, Mishimoto, Trick Flow, and maybe Black Forest? The things that I am paying attention to are the filtration elements and the distance between the inlet and outlet. Along with wanting a dipstick type versus a window that you wouldn't be able to see. I don't like exposed clear tube set up neither because that's just something else that will end up being dirty with build up. I think the Trick Flow has a stupid little circle window but, I am trying to see how well their filtration/baffle system is. Which is difficult to find for most cans, such as the Weapon R box like catch cans. Thanks for your time. Wish me luck! Oh, would you happen to know what exactly would require a 3 port vs. a 2 port? I know that I don't need one with a breather though.
Anyone have any suggestions for an AOS for a Lexus IS250? Please don't say the rr-racing one since call it an AOS but it's just a catch can. It doesn't send oil back into the system and you still have to drain the can manually periodically. Wouldn't you just be able to use this AOS with customer measured hoses?

The Cobb and IAG aos' are very similar besides a few minor details. You can't go wrong with either of those two which are the ones we recommend, but having one will be better than not.
is no only oil coming out the PCV is also water condensation from broken/burned oil, personally I dont want all that buildup water go back to my engine oil. In my opinion the catch can is the way to go.
Would there be any issues with warranty claims? I've been looking around for warranty safe mods but catch cans and AOS never make lists for some reason.
@@SubiSpeed don't mess with my head. I have been getting stuff for the wife's 15 fxt and I'm super jealous with all the products you have for that model.
Install video please!! Many videos out their but aren’t really showing how to do DIY. I do have a question regarding the Invidia Q300 if anyone else would like to chime in please do so. I have a 2015 STi with a Q300 and noticed the passenger side exhaust vents/smokes more than the driver side exhaust. Is this normal? Any idea on why??
I'll do my best! As for the exhaust question, the exhaust gases will always exit through the shortest / path of least resistance which is why you see it come out more on one side rather than the other.
Since the WRX is the newer platform with a new engine, there have not been many videos covering installs. Whereas the STI has plenty of videos out there since it is an older platform.
Sooo aos is for lazy ppl that dont want to check/empty a can and dont mind that junk being dumped back in the engine, and a catch can is for ppl that dont want that junk dumped back in the engine/arent too lazy to check and empty a can? Lol
@@sastsxx just what the video made it seem like. I think the video is saying a catch can wont return the substance back to the engine and needs to be emptied from time to time, while the aos does not require emptying but returns the substance back to the engine. Maybe i watched a different video 😂

@@Menace_sti already in the works!
What’s the maintenance on a Aos
Not much but you still have to clean it time to time as oil does gum up with time
Any plan to extend products to the 08+ WRX model?1
Maaaaaaybeeeeee
@@SubiSpeed don't mess with my head. I have been getting stuff for the wife's 15 fxt and I'm super jealous with all the products you have for that model.
Do i need a tune for this one ?
Go ahead and do spme research 🤷🏻♂️
Access port giveaway anytime soon?
Probably not :(
What kind of "rally ish" tires do you recommend?
Gonna be completely honest, I haven't really done a lot of rallycross or anything of that nature so I couldn't comment on that.
@@SubiSpeed What about general offroad or snow tires? Thanks
For snow tires you can go with Blizzaks or if you're looking for a very affordable snow tire take a look at the General Altimax.
@@SubiSpeed Thanks!
Install video please!! Many videos out their but aren’t really showing how to do DIY.
I do have a question regarding the Invidia Q300 if anyone else would like to chime in please do so. I have a 2015 STi with a Q300 and noticed the passenger side exhaust vents/smokes more than the driver side exhaust. Is this normal? Any idea on why??
I'll do my best!
As for the exhaust question, the exhaust gases will always exit through the shortest / path of least resistance which is why you see it come out more on one side rather than the other.
SubiSpeed Thanks!! The Q300 seems to be split evenly in the center to both exhausts which I find strange for it to smoke uneven

Why so many install videos on wrx than sti?
Since the WRX is the newer platform with a new engine, there have not been many videos covering installs. Whereas the STI has plenty of videos out there since it is an older platform.
SubiSpeed so the engine bay are all the same? Where fitment and putting everything on the right place are the same as all?
The engine bay itself may differ a bit but the engine itself is the same and installs will be practically identical if not very similar.
Pants or shorts?
Shorts.
@@SubiSpeed kilts 😎
Why doesn’t the STI have a shift stop? I have a 17 STI but there are only shift stops for a wrx.
The STI shifter design is different than the WRX and doesnt allow for one.
Moroso advertises their product as an AOS but its more of a catch can in comparison to the IAG right?

I have a question, whos the dummy paying 450 bucks on a metal cylinder with a filter inside?
All the good people are gone now. Looking back is sad. Nobody watches anyone
Hey what’s up
Just trying to stay warm here in Iowa. What's up with you, Danny?
Trying to stay safe with the 8-9 inches of snow we’re getting her in MN 😂
We're getting beat up down here as well so we know how you feel!
Can you turn the music down so the music is not louder than your speaking voice? Almost lost my ears just now with that intro.
Gotta make sure you're awake!
@@SubiSpeed let me sleep until the air oil separator part starts.
First like!
Sooo aos is for lazy ppl that dont want to check/empty a can and dont mind that junk being dumped back in the engine, and a catch can is for ppl that dont want that junk dumped back in the engine/arent too lazy to check and empty a can? Lol
Not at all lmfao. This was a hilariously ignorant response tho
@@sastsxx just what the video made it seem like.
I think the video is saying a catch can wont return the substance back to the engine and needs to be emptied from time to time, while the aos does not require emptying but returns the substance back to the engine. Maybe i watched a different video 😂
