GrimmSpeed Blow Off Valve Flange Gasket - 02-07 WRX / 04-20 STI

The OEM Subaru Top Mount Intercooler Gaskets are pretty weak, and will eventually give out. But fear not, GrimmSpeed has answered your call. Their blow off valve flange gasket is 3 times thicker than the OEM unit, it also contains an inner metal layer that will prevent blow outs. 

The TMIC surface, and the BOV flange never seem to truly mate to each other, That’s where the 3x thicker BOV gasket‘s extra thickness comes in handy, creating a better seal for better protection against leaks.
