Damaged my oem bov gasket when re installing the intercooler and not paying attention. Although, it wasn't leaking I replaced it with this to have a piece of mind.

  • AnswerQ: 08+ WRX  jvigil105118 2 years ago

    Why wont this fit the 08+ WRX?? I don't see one for the 08+ WRX on your website. Can you get it?

    • A: If you look at your car, you will see that your BOV shape is completely different then this one. Contact us directly and we can look into getting that gasket for your vehicle to work with the stock valve.

  • AnswerQ: Suitable on 2006 wrx with aftermarket tmic?  asetemadi48283 4 years ago

    I'm replacing my stock TMIC with a process west unit. Will I be able to use this gasket with the PW and the stock bypass valve? My understanding is that the rubber o-ring gasket on the 06/07 wrx models only applies to the stock tmic. Thanks in advance.

    • A: Hello, From my understanding this gasket will work with all 2002-2007 WRX and 2004-2012 STi stock blow off valves. Since the Process West retains the factoy style blow off valve flange this should work great. The rubber o-ring gasket from my understanding was not introduced until the 2008 for the WRX.

    • A: I believe you are correct. You should be able to use this gasket on your stock 06/07 WRX valve as the flange shape is identical and is the same shape that is machined with the Process West top mount intercooler kit.
