GrimmSpeed Blow Off Valve Flange Gasket - Subaru WRX 2002-2007 / STI 2004+
Manufacturer Part # 020023
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.

GrimmSpeed never disappoints! Their products are all of the highest quality and this gasket is no exception. The gasket that shipped with my new BOV was junk, the GrimmSpeed gasket was recommended by others RSD and they were correct. It fits perfectly and seals nice and tight.

As good if not better than the stock gaskets. It seals like its supposed to.
