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.

Unreal
2017 WRX here. Under heavy acceleration it would always register -1.76 fkl knock and -1.41 during cruising. Car is stock besides the Cobb tmic v4.00 ots map. After install it revs much faster, and fkl went into positive values. After removing the stock pbv i can open it with as much vaccum as puffin a cigarette, but not with this. It really revs like an old school Honda. I should have done this earlier before banging my head with changing sparkplugs on the damn car

Installed on a '14 FXT. Removal and install was simple and easy. I changed out the leaky OEM for this and what a difference it made. It was noticable enough for my wife to acknowledge unprompted. I chose this one after seeing a video on their site.

Great supporting mod
Relatively easy install,maybe 2 hours total, holds boost better than stock, sounds great with aftermarket intake.

Great upgrade!
The install of this valve added power and response time to the turbo.This is due to leaking stock valve. A bonus this new valve makes great sounds.

Wrong color, I ordered black and they sent me a blue one.It does holds boost much better, in turn the turbo doesn't have to compensate for the BPV leaking pressure causing the turbo to run out of airflow.This helps keep the air flow efficiency up, cooler air and less likely to cause spark knock.

Absolutely love it. Has the delicious Stu Stu Stu sound ...
Absolutely love it. Has the delicious Stu Stu Stu sound I've been looking more, it fixed my boost leak with the pos oem bpv. Up to 20.5psi and holding strong compared to the 15.4psi that I was getting with stock. Great quality part and super easy to install. Great work boomba and map, keep it up.
