Features & Product Details

The Cobb tuning Blow Off Valve which is also a hybrid valve. Hybrid blow off valves come in 3 different valve configurations.  You have fully recirculating where you utilize the provided elbow off the blow off valve where it recirculates back into the intake.  The second option is fully atmospheric which is going to give you the loudest sound, however the air does not get recirculated back into the intake, and the ECU will think the air is provided which will create a slight rich condition in between shifts.

The Hybrid option gives you a 50/50 valve.  50% vents back into the atmosphere, while the other 50% gets recirculated back into the intake. You can remove the flange plate on the rear to make that happen. 

Compared to stock, the Cobb Tuning Blow Off valve has been crafted out of high grade anodized aluminum, and overall is a better upgrade than the OEM unit whether if your supporting more boost, or if you’re stock.  The design is close to stock compared to other blow off valves as well. Overall, you will be satisfied with the Cobb Tuning Blow Off Valve.

Light and snappy bpv 7 years ago

I am stage 2 with stock turbo at 20 psi. I noticed I was only peaking 19 psi on some pulls so I ordered a go fast bits bpv. It was too heavy and I had flutter at low boost so I ordered the lighter cob piece. Super easy to install because it's 2 screws and a hose, without putting the stock nose back on. It's pretty much ready to go out of the box. I gave it 2 turns to the right to tighten up the spring a big. Vents between 2 psi and 20, holds all my boost and sounds fantastic. Obviously another great product from cobb

Recently built my forester XT, and wanted a stock look and sound. this BOV kept the car subtle, but still gave just enough boosh to know it wasn't stock if i wanted to let people know.

This valve is absolutely amazing. Installed it a month ago. I come from a WRX with the COBB BPV. And now I own an STI. Let me tell you that the stock BPV won't handle 21 psi like this COBB one. After I installed it boost felt smooth and recirculating sound was improved from stock. Now on 100:100 sounds like if it was 50:50. Perfect sound, fitment and result. Thanks RSD you guys sell nothing but the best.

Super easy to install, includes everything you need except a gasket. Eliminates boost lag and sounds great overall! Definitely worth every penny (&the processing and shipping is fast too!)

QUESTIONS & ANSWERS

  • Q: Bpv   Jmelody3 years ago

    Will this reduce crackles and pops noises we all love?? because at stock I would here more pops and crackles and with it on I verbally hear it or not as much especially when down shifts
    • 0 of 0 people found the following answer helpful

      A:  This will increase the flow of air which may reduce the pops and crackles we love, but in the name of efficiency.

  • Q: Cobb XLE BOV adjustments  The angry badger6 years ago

    I recently bought a cobb xle bov for an 08 wrx sedan. I have an cobb sf cold intake installed, so my question is i been hearing the bov can be recirculating, 50/50, and something else. So how to i change my bov to those settings and which one would be the best for my car. Also so i need to adjust the allen screw on top?

  • Q: backfires with no tune  bjg92239497 years ago

    if i have a 2012 stock wrx and i put this BOV on without a tune or anything and make it 50/50 will it cause any type of back firing or anything?? i guess basically im wondering if i put it on a stock engine with 50/50 so i can get some noise from it, will it cause a back fire or any other problems?? thank you!!
    • 0 of 2 people found the following answer helpful

      A:  50/50 BOVs on Subarus usually cause some backfiring, but it should be minimal with this valve, and backfiring generally does not hurt anything.
