This high performance recirculating blow-off valve is precision machined out of aircraft grade billet aluminum. It features an internal brass piston design and is pressure tested to withstand up to 75psi, allowing it to compliment even the most aggressive turbo builds. Spring pre-load determines the pressure differential required across the piston before the BOV opens and releases the pressurized intake charge. Designed to be a replacement for the OEM bypass valve and is available in 4 different colors.
-Larger cross section compared to stock
-100% recirculating
-Higher flow
-Pressure tested to 75 PSI
-Easy install
-No need for re-tune
Installation is simple and all mounting hardware is included.

Greetings all. I just installed my new Boomba bypass valve on a 2018 WRX. I test drove it, and all felt great. My boost gauge showed a peak of 22.9 psi after one pull. I don’t know what it showed before with the stock part. Wish I had noticed.
Like “Subaru WRX” says below..... our newer cars are different than the one in the video. I’m glad he made his comments on this matter. It did help. Thank you, Sir.
So I just got done installing this in my 2017 wrx...dude, this thing feels like it makes a HUGE difference. I'm not exactly sure how much but I definitely felt it in my pulls.
Thanks for the positive feedback! We're glad to hear you are happy with the piece! Probably picked up some PSI that your OEM piece was leaking off.
Boomba Racing if I reinstall the factory bpv, will that be ok after the hose being trimmed?
Installed on my 2020WRX. Definitely a difference with throttle response. Much quicker pick up between shifts. Nice flutter sound!! Thanks Boomba Racing. Highly recommend as a first mod for your WRX. Not a bad way to get some extra gains.
JP's WRX yes, slightly.
It fit and lined up perfectly on my 2018 WRX without trimming the bypass valve connection on the turbo inlet. Some trimming may be required on older FA20 WRX models though. I however paired this with a Perrin charge pipe, Apexi drop in filter and a Perrin turbo inlet pipe and love hearing the turbo spool and bypass valve sounds that are audible. On a side note, 2015 to 2017 WRX's have an intake silencer/milk jug whereas the 2018 and newer ones do not have that on the factory air box, which can affect hearing the turbo and bypass valve
@@Khans0120 hey ur comment is scream that I have finally found someone that can tell me why I can't hear my boomba bpv on my 2019 I also have a pretty Loud axleback exhaust if that matters please help me out!!!! I'd appreciate it a ton
Do you have any other modifications done to the car, preferably to the air intake so the engine breathes easier? If you haven't removed any of the plastic intake ducting and replaced it with something that lets the air flow freely, you really won't hear any bypass valve sounds at all. If you want to know the most audible method of getting the sound, though, it will require you to install an aftermarket cold air intake and get the car pro-tuned so the engine does not get put in danger. On a side note, the Cobb OTS tune is not the way to go because that tune was not designed for your car specifically. That Cobb OTS tune possibly could work fine with your cars engine, or it could become a ticking time bomb due to your car residing in a different environment than their shop cars
@@jamessanderson3498 what do you need help with? I have the same set up on my 20’
This is a good install video; especially like telling which tools to use :)
I think my 2018 WRX looked a bit different, but the same enough that this was a perfectly good guide.
I just ordered mine! I cant wait to put it on! I just installed Cobb Port/SF 1 intake on my 2020 WRX. Thanks for the Vid!!
Thanks for choosing Boomba!
@@BoombaRacingEasy to install. Took 45 mins or so. Sounds fantastic!! Thank you for the great product!!
Did you use an OTS tune or an E Tune?
Jay Lacson did you need a tune to run it or no
@@darrenhernandez2459 No tune needed
Good install vid. Boost comes on quicker, worth the hassle and money imo
lmao, this has nothing to do with making boost quicker. Think you need to take some schooling on cars.
My 2017 Wrx had a wiring harness and a hose instead of just a hose with a clamp. they have changed it. But it still went on fine
Thanks for the heads up! Glad to hear the install still went smooth.
Derek Camacho How did you remove the hose and the wiring harness??
EverythingRandom just pull straight up on the hose
What year is your car, Derek?
BoombaRacingInc 2017
What are the consequences of not trimming the inlet pipe?
Installed easily, great solid design and difference with throttle response, once again boomba for the win
If i want to install the stock back on, would I need to buy the tubing that was trimmed down??
@Boomba Racing -- would love a reply!
I’m guessing no. Since hardly any is trimmed off, there still should be plenty of seal for the stock BPV. If you’re concerned, you could zip tie or clamp the end of the connection to ensure a seal, but I think you’d be okay.
Installed mine tonight. Thanks for the video. I did not have to trim anything on my 2019.
BlueFA20 WRX great to know!! My bpv is coming in tonight for my 2019 base wrx and I didn’t wanna have to do too much extra
JP NPC I also have a 2018 WRX and I did not have to trim the bypass valve connection on the turbo inlet at all, it fit perfectly. I however paired this with an Apexi drop in air filter, Perrin charge pipe and Perrin turbo inlet, and I can honestly say that I love hearing the turbo spool and bypass valve go off due to those other parts amplifying the sound a bit. Our 2018's and onward do not have intake silencers/milk jugs like the previous years so that lack of restriction allows us to hear the turbo and bypass valve a tad more without the need to go with an aftermarket air intake setup
Hey when i was cuttin the hose i cut too much now i leak boost what is that hose called to replace please help
installing mine tonite, will be uploading a video. Hopefully it lives up to the hype guys :P
I’ve had this BPV for over 6 months now and it’s been great. Recently when I hit around 10 to 12 psi the boost hesitates and stutters for half a second then it acts normal and starts climbing again when I’m on the throttle. My DAM on my accessport drops after hard pulls. My tuner said he thinks the BPV has a leak and is causing it. He even went as far as saying that the stock bpv is better then the boomba from personal experience. Have you guys heard of this problem before?
any updates on this??
Updates?
I have that exact problem with my stock bpv, changed the charge pipe and new cold air intake is better but still happens!! Weirdest shit ever
Ive had a similar problem but mine turned out to be my HPFP wasn't able to produe enough pressure so i got a Nostrum and it fixed the issue. ask youre tuner if it could be a fuel pressure isssue
Yes my tuner said the same thing here out of Houston. I have the boomba but have not installed for that reason.
Go back to the drawing board and make it so that we don't have to cut/trim our stock hardware to fit your part. Make it true plug and play.
Depending on how the vehicle was assembled, the line may have a kink in it if it is not trimmed when installing our BPV. We do have customers with our BPV installed without trimming that inlet. Even if you trim that inlet, the car will still be able to be returned back to stock should you ever want to go that route.
I only trim like 2MM and fits well but the the video instruction isn't a good representation of the 2017 model. My turbo inlet layout is different from their model car they were using. I skipped most of the step that recommended. I worked from an angle on the side instead directly under it. I was able to remove the stock BPV without removing the turbo outlet vacuum hose. I be honest I don't feel like reinstalling those cover that muc
If at all possible, can you upload a 2020 WRX version? The hoses and clamps on the turbo inlet do not match the video. It has a weird clamp and sensor assembly. Thanks!
is it a bypass valve or blowoff valve? the title said bypass valve but dude I in the video keep saying blowoff valve.
Its a 100% recirculating bypass valve
Is an aftermarket CAI needed for this?
Should this be installed on an STI? Or is this just for the wrx?
Hey guys can someone please help me.
I have a 2020 wrx sti and I live in Australia. Recently I have purchased a boomba BPV and I have been told it can't be installed in my car. Is that true ?? If not would it be the same as this video. Thanks in advance
This particular BPV is this video is specific to the 15+ WRX FA20 motors. The EJ25 motors in the STI's use a different BPV, which can be found here: www.boombaracing.com/wrx-sti-recirculating-bypass-valve-bpv/
@@BoombaRacing ok thank you so i need to purchas the one from the link for my 2020 wrx sti??
installed it but i am getting ZERO noise, no flutter at all from the bypass valve. plz help.
The instruction video was great. I installed the valve in under 2 hours and didn't trim the holes. Everything seemed to go together well but I dont hear a flutter or notice any gains in pressure. Did I do something wrong?
Yikes did you ever figure out what was wrong?
I called the company and asked about it. The first question they asked was if I had an aftermarket CAI installed. I dont. Therefore, it wouldn't work properly until I install one.
I just did this as well. Doesnt flutter like in other videos it sounds kinda stock. So you need an aftermarket intake to get the flutter
Representing the CVT gang here, does this BPV work for the cvt and does it still sound alright without an intake or tune?
Still works on CVT! You'll still be able to hear the purge sound when you let off the throttle, but wont be as loud with OEM intake
@@BoombaRacing I’m curious, I have a drop in k&n panel filter but I’m not hearing the purge sound at all, I’m wondering if I forgot to connect a hose or not, people are telling me I did something wrong and some r telling me I’m fine so I’m unsure
Did u ever get the sound ?I'm having same issue
If i have Stage 2 tune(EBC,Catless TBE,TGV Deletes,TMIC,Chargepipe) would my tuner have re-tune my car for this blow-off valve?
Hey there, we have customers running this piece on totally stock vehicles as well as ones that are highly modified. Since this piece is recirculation, a re-tune is not needed. However, you may see even smoother boost if you do get a re-tune specific to this part.
Im not getting that “flutter” sound like most is that bexause im not tuned? And have a stock intake?
Hello! Yes, to produce the flutter sound the BPV and an intake is generally utilized. The part is a bypass valve and does not vent to atmosphere hence not hearing the flutter sound. Hope this helps!
Would I need recirculation kit with boomba bpv? I have aem charge pipe
Will this work with grimspeed aluminum turbo inlet ?
U don't need to torque the 2 bolts from the turbo ?
Can you timestamp where in the video you are referring to?
BoombaRacingInc 3:20 to 3 :27
You want to make sure they are tight, but nothing overly crazy.
So I recently ordered a Boomba bpv for my 2018 wrx but the person didn’t include the extension vacuum line and I’m not sure what to do now .. I can’t find any for sell
Amazon ? Did you find it what did you end up using ?
Do u have to Chang map in cobb after install that?
What does it sound like????
Please explain to me why you’re installing a BPV and calling it a BOV in your video??? I want to buy this but this just drove me fucking crazy.
Are these the same directions for the 6th gen Outback?
Hi! This product was designed for the FA20 engine and unfortunately will not fit the FA24 on the Outback. This is the product that will work for your turbocharged outback: th-cam.com/video/WVVtlSCNj1c/w-d-xo.html
Thank You@@BoombaRacing
Would be perfect if it weren't for trimming plastic off of the piece the boomba fits onto.. will it make it impossible to reattach the stock part in tje event of selling the car and getting the stock bpv on?
Some customers have made it work without trimming that piece. However if you ever do go back to stock, you can simply buy a new piece of hose from an auto parts store and swap it on. Very easy thing to do.
How important is it to trim this piece? Can I just force it in as much as possible without trimming are there any negative effects?
Hey so i installed it exactly like this but it doesnt flutter… it sounds like i have the stock bpv on
Any update? and do you have any other mods at all?
is there going to be a test on this
I'm curious about this as well. I just ordered boombas shift kit last night and was thinking about this and my tuner told me they have never seen a leak in the stock bpv. And my car is pushing 325 @ the wheels. And told me never to get a valve unless it was 100% recirc which this is. Is a retune required for this install?
We have heard of some tuners that have found leaky BPVs on totally stock WRXs. You can use this part on a vehicle that is totally stock, or heavily modified. There is no need to retune after installing this piece. If you are already working with a pro-tuner, it doesn't hurt to send them some logs to see if they can squeeze you out a little more power after the installation of this piece.
Cant i uses this in a automatic wrx
Hello! Yes, this will work on an automatic model wrx as well!
I just installed my bpv today and realized that, the hose you guys say to trim in the video, has a split half way down the hose. Anybody know the part number of that hose? Going to need to replace it. Its the one that goes from the bpv to the turbo inlet. Thanks
I realize that this reply is a year late but did you consider buying the reinforced silicone Perrin turbo inlet for our cars that's nearly $300? It will save the inlet from obtaining leaks in the future, but yes I also agree that the Perrin turbo inlet is severely overpriced for what it is
S Khan yeah ended up having to buy the whole piece from subaru. It was called the air duct intake or something. Looking back i didnt know that the turbo inlet would be a full replacement for that part, or i would have went aftermarket. Ive since traded my subaru in for a truck
What year wrx/STI's can this go on. Cuz I have a 2005 WRX and I'm look for a BPV or BOV That doesn't need a tune. With this work on my 2005 wrx?
This BPV is specifically for the 2015 and newer WRX.
Is this relatively the same for a 2014+ Forester XT? I have an 18 and I’m trying to install this myself but nobody has videos for it that are decent
Yes, as long as your XT has the FA20DIT, the installation will be basically identical.
i just wanted to make sure I don't have to tune my 2016 subi wrx if I install this boomba bov! just remove old bov and install new boomba bov with no issue's. right?
This piece is as plug and play as it gets. It bolts right no and works with no special tuning!
Wondering will be the installation way same for the wrx 2016?
Is this BOV applicable to 2015 STI and has there been any issues, check engine light, Boost leak, backfiring etc? TY
This BPV is non adjustable and is meant for the WRX only, not the STI. This piece works on totally stock vehicles as well as extensively modified ones. It will not cause any issues.
What might cause my Boomba to not flutter? Help please!!!
The sound is much more noticeable with an aftermarket intake
can i still hear the flutter sound if i install it on my stock wrx??
yes you will it usually gets louder
Quick question when you re installed the stock inlet what torque did you use on the two 10mm bolts? I just did hand tight then a quarter turn. Wondering if that’s relatively close ? I saw somewhere on a forum it’s around 10ft just trying to make sure my install was smooth.
You should be fine. If you are worried, pop under there and give them a snug!
Does anyone know if you need a tune To use this bpv. Pretty new to the whole car stuff and just wanna get some certification,
No tune is needed to use our BPV
Question! Hi- I just bought two of these for the twin turbo 2015 wrx - I have a Cobb Stage 1 Waste Gate tune with a Mishimoto intake - I want to put them in this weekend but was considering to atmosphere them. What are the take of pros/cons on this?? Im not so much worried about the fuel ratio but rather the loss of sufficient engine power or a disrupt in the epu thx!
Happy to answer that for you, the WRX is MAF tuned, meaning that you can't vent to atmosphere. This is because the air that you would be venting, is already metered.
Perfect thank you for the fast response !
Joe Pierce it’s twin scroll not twin turbo 🤦🏼♀️
francis888milot realized that shortly after
Is an aftermarket cold air intake required to hear the flutters?
Hi, if you're looking for flutter, you will hear it most audibly with an aftermarket intake!
@@BoombaRacing so if you have the stock intake you won’t hear a difference?
@@itsDarrell With the stock intake the BPV will still increase the amount of turbo noise that you hear but will definitely be quiet without an intake. The BPV is designed to hold higher boost pressures than the stock BPV and aid performance but we do recommend an intake if your goal is turbo noise.
@@BoombaRacing my goal is to keep my warranty and have as much of the sounds as I can get without a tune
@@itsDarrell There are a few aftermarket intake options we've seen that do not require a tune but we cannot provide any guarantees on those. As for warranty, the part has to be shown to have caused the failure to legally deny warranty service, we'd recommend developing good relationships with your dealer!
Anyone break a bolt?
help
I have the stage 1 eTune by MAPerformance along with a Nameless Muffler Delete CHE.
Would like to do this someday but concerned about stalling, etc...It seems relatively simple to install and wish I knew for certain that this would be far superior to the stock one. It seems that way per your videos though. Hmmm...what to do.
Thanks!
You will not need a special tune to run that piece on your car! Our BPV operates in the same way as stock so there is no need to worry. We have customers running these on stock vehicles as well as highly modified ones. It holds boost much better than the stock piece.
BoombaRacingInc just ordered mine today! Hopefully all goes as planned.
Thanks for the order! Let us know if you have any questions!
BoombaRacingInc Installed 3 weeks ago on a 2015 WRX with new air filter (stock) and MAPerformance Stage 1 Etune! Definitely pulls harder now. Impressed. Maybe just me, but I have better MPG now for some strange reason. Gonna fill up today and I am 367 miles whereas before 320 was the norm at complete empty.
THANK YOU, BOOMBA!
Thanks for the positive review! We love hearing good reviews from our customers!
It says on your website that it's a pre-order? I've seen people with this already.. is it a new version or something?
It says that because we are currently out of stock.
BoombaRacingInc so they'll be available on the 19th? All colors?
Yes, we will have all back in stock then!
What kind of tune do you need in order to have the BOV?
None at all. This can be installed with the stock tune
Where I can buy the vacuum line replacement ?
Hi! Shoot an email to info@boombaracing.com and we can get you all set up!
I don't live far from Wooddale, can this be purchased there and installed by you guys?
You absolutely can! Shoot us an email or give us a call to set up a time to come in.
braz989 free installation with purchased??
do you still have to trim with the new cobb and gs cast aluminum inlets ?
Hi! We know that this part fits the stock inlet but are not certain about fitment on the aftermarket options. If there is a rubber connector for the aluminum inlets it may be possible!
@@BoombaRacing yes it's a upgraded silicone coupler
@@peezy304 Great! As long as that is the case and the inlet is routed the same way as stock the fitment should be good!
Can these be used on a Nissan 300zx? Since you guys don’t make a kit for them
We do offer a universal BOV if that's what you're looking for.
Looking for the sound of this one but to be run as a pair of recirc valves on a 90 300zx
@@livingwastland We can't say if this would work or not
how different is the install if you have a front mount intercooler?
We're not sure, We installed this on our shop car which has the factory intercooler.
its the same
that video is with EBCS right?
Negative.
What is the purpose of cutting off the 5mm off. Is it required?
We say to cut the hose because it may be kinked if it is not trimmed after installation. We have had a few customers that have installed this piece without trimming the hose, but in most cases we find that it is necessary.
Will I be able to reinstall the stock bpv if i trim the hose?
Yes there will still be enough material left to return to stock should you ever want to remove our BPV.
Do you need a tune for this
No, this BOV is completely plug and play and can be used on stock and aftermarket tunes
Does the Boomba BPV void any dealer warranties?
When it comes to warranty questions, we would advise you to speak to your local dealer. Every dealer is different when it comes to warranty claims on a modded vehicle. In short, no but again every dealer is different.
Ok. Thanks.. I just bought the car 2 weeks ago. The BPV would be my first upgrade.
Does this work with just stock tune?
There is no tune required for this part.
Does this mod void warranty?
When it comes to questions like that, we recommend talking to your local dealership to see how they are in regards to mods.
Does this offer any performance qualities?
Yes this is a huge upgrade over the stock BPV which is known to tear and leak boost. The stock BPV features very poor construction and is made from cheap plastic and rubber and features a very flimsy spring. Our valve has aircraft grade billet aluminum, a brass piston, and Viton O-rings and is tested to 100 PSI to ensure leak free operation. All of our BOVs also carry a lifetime warranty to the original owner. Our BPV helps to eliminate boost spikes and holds pressure much better than stock. Check out this video to see the power gain we picked up! th-cam.com/video/QFyw-ktSQEQ/w-d-xo.html
Yes, and the best part is you don't need a tune with this, either. Approximate gains from this is a surprising 10-15 HP over the stock piece. Just got mine in the mail today. :D
^^ They responded before we even got the chance! lol
Do I need a tune if I put this on ??
+Marcos Hernandez you can run this piece with or without a tune. We've got many customers running this piece safely without a tune.
+BoombaRacingInc do you have a video of how it sounds ??
Marcos Hernandez Yes we do, as seen here: th-cam.com/video/UKmIt0IlUtE/w-d-xo.html
I'm sure u can install this without trimming that piece
Some cars can, some cars you have to trim it.
anybody using this bov? and how is it no boost leaks.
+LatinoAD Recent review from a customer: "The installation wasn't hard at all... the video instructions were spot on. With an air intake, this sounds amazing! I really love this product, you'll be really pleased with it."
its a good bpv watch one of my vids it sounds good too
CEPHALEXIN323 Thanks for the kind words!
LatinoAD j
I got a check engine light as soon as I turned car on. Is this normal?
A boost leak would most likely cause a CEL. I would make sure sure all clamps are tight and the vacuum line is secure.
@@BoombaRacing It cleared itself up after second start up.
I wish there was one for my 2009 STi
