GrimmSpeed Head Gasket Set 2015-2021 WRX

DESCRIPTION

Feature-packed, these gaskets are a perfect fit for any engine build, from basic refresh to a high horsepower track monster. The GrimmSpeed Head Gaskets feature a multi-layer steel (MLS) construction, in which multiple grades are used to provide optimal surface and combustion chamber sealing as they are torqued down. The top and bottom layers feature a Nitrile Rubberized Coating that helps accommodate a rougher RA surface finish of up to 50microinch. This acts to better seal the non-critical areas of the gasket. In addition, the gasket edge includes a folded stopper layer that allows for optimal sealing for the combustion chamber. This is done to help reduce the chances of combustion gasses causing head gasket failures under extremely high cylinder pressures that built engines can experience.

WHY?

The FA gaskets were designed to be compatible in both FA20F DIT (WRX) and FA20D (Subaru BRZ, Scion FRS, Toyota GT86). Meaning that it will be just as much at home in a lower power NA build as it will be in a high power boosted application. We’ve outdone ourselves this time, The GrimmSpeed Head Gaskets carry on the legacy of quality that you’ve come to know from our other extremely popular gaskets.
