Does anyone know the flange size of the BOV on a wrx? I'm after a HKS SSQV BOV and the flange size is this flange adaptor 25mm.

Cheers Kev

 

This may help you, although anyone selling these should know what to supply from the option selected as they should be sold as car specific. From the picture, you'll see the 'new age' flange is very thin. The most important aspect should be the shape, as the top of the flange needs to be flairly flat to clear the 'breather' pipes.

I'm guessing a need a adapter piece to get it too fit correctly, but has anyone got the HKS BOV SSQV? and maybe had any experience with fitting.
