Add horsepower, quicker response, and reliability with the Perrin blow off valve. A must-have replacement for the leaky, slow responding, and plastic OEM blow off valve.
Features:
With large inlets and outlets, the PERRIN Blow Off Valve is sized perfectly to relieve any amount of boost pressure without fear of compressor surge. Don’t be fooled by giant oversized blow off valves, these inlet and outlet sizes were chosen to ensure the perfect balance of flow and to maintain boost in your system, without ruining response by dumping too much boost.
It is vital that a blow off valve for your WRX and STI recirculates the air back to the intake track to maintain proper air-fuel ratio and driveability between shifts. While this can be set up as a vent-to-atmosphere style blow off valve, we only recommend that on cars running aftermarket Speed Density type tuning (cars without mass airflow sensor).

OEM unit had 272,000 miles on it and couldn't hold enough boost to match my build. Perrin products have always served me well!
Fits nicely on my 07 LGT, LOVE IIR
It was a simple install, takes no more than 30 min to install and sounds great
Th
Amazing!! For starters, install was super easy!! I recommend if your going from OEM BOV to this do yourself a favor and get a new Gasket just because. The sound difference between this one and the stock one is out of this world!! I've gotten so many compliments on just how my car sounds since getting this BOV it's wild!! I highly recommend if your going to get this to also get the Perrin Short Ram V2 Intake and 2.5 in Turbo inlet hose. You'll notice the difference in sound and power immediately
Had an HKS BOV prior and couldn't be more happy with the switch to the Perrin BOV. Excellent product that came with excellent service!
I don't think I've ever seen such craftsmanship on a BOV/BPV. Great product, and great service!
I ended up purchasing this and it was incorrect due to me not reading the description correctly but I was able to send it back and get refunded in a pretty reasonable amount of time and get the right part orderd.
This comes with excellent instructions detailing the installation procedure. Also come with all the hardware and tools needed for installation! Installation was super easy and the unit works great in my car. Build quality is also superb!
Great BOV. Fast shipping great website to get the nice mods you need for your car
