Review on π Turbosmart TS-0203-1209 Kompact Plumb Back Blow Off Valve for Mazda/Subaru - Black, Enhanced SEO by Richard Jarvis
Fixed my squeaking/whistling when accelerating.
Great things. There was an annoying whistling noise from my old BPV not closing fast enough when I let off the gas while driving conservatively. I noticed this when I entered Stage 1 taking Cobb SF. I removed the air intake and put it back in stock and still noticed the noise. So I decided to bite the bullet and buy this one, hoping it won't displace my WRX. Sounds like stock with a shorter "CHHH" when I switch to WOT. Fits perfectly on a 2010 WRX Hatch, literally took me less than 5 minutes to install and completely fix my problem. The pedal is also more responsive now, but not by much.
