Q: BOV caceres4468 6 years agoAnswer
will this fit on a 2010 wrx?
A: Out of the box this will NOT fit on the stock WRX. The adapter that is included with it is meant to be welded straight onto a intercooler pipe. To get this to work on the factory top mount would require a custom flange to be made.
