[Installation Guide]

See the video below to observe how badly the stock BPV leaks! We were able to pick up 15 hp and 9 tq from switching to our piece.

This high-performance recirculating bypass 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 complement 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, it is available in 4 different colors.

By applying equal amounts of air pressure to both the charge pipe side as well as the vacuum line side of a BPV, we're able to simulate real-world boost conditions. Doing this allows us to test the overall construction of the BPV, including the ability to check for leaks.

Key Features:

Larger cross-section compared to stock
100% recirculating
Higher flow
Pressure tested to 75 PSI
Easy installation
No need for re-tune

Installation is simple, and all mounting hardware is included.

15+ wrx bpv

Absolutely love this product. I had a GFB hybrid bpv on my wrx before and it was a leaky POS. Put this one on and can instantly tell a major difference. The smooth acceleration is a night and day difference between the two bpv. Thanks again boomba for making a great, affordable product!

Great piece

Installation was straightforward, build quality looked good, and functioned as advertised. A great replacement for any leaking or damaged BPV

Amazing!!

This bpv is awesome. If you're running an aftermarket intake adding this as well is totally worth it. The Boomba sounds great and it eliminated this really annoying high pitched chirping noise that I was getting from the stock bpv. Well done guys!!

BPV

Posted by Joshua Antunez on 19th Jun 2020

This is honestly the best bpv you can get for a Subaru. The installation was very easy and straightforward little to none modifications needed to fit. Throttle response and the turbo flutter feels and sounds amazing. I would most definitely recommend this product to anybody in the market for one.

Nice Flutter Sound

Posted by Kev Forester on 15th May 2020

The boomba bpv feels very solid and high quality. Installation on the forester XT was pretty straight forward but required me to look at several YouTube videos to make sure how to disconnect hoses from the stock bpv and how much to trim away for one of the hoses. The boom a bpv fits right where the old on sits. With the combo of a aftermarket air intake, I was able to hear the flutter sound from the bpv inside the car. It wasn’t too loud, it’s exactly what I expected.

2014+ Forester XT BPV

Posted by Deadend on 9th Jan 2020

Solid and nice looking machined piece that unfortunately will not be seen. smaller than the stock plastic one. it's not the psssshhh sound that hybrid bov produce instead it produces a nice flutter like sound. I may be in a small group of people here but I wish it was louder, don't get me wrong you'll definitely be satisfied with its volume I just like scaring people when it releases. I definitely recommend it as it's a part that even a novice like myself was able to install on my own.
