At GrimmSpeed we have worked with endless amounts of aftermarket gaskets, none seem to work as well as the multi-layer steel oem style gaskets. The issue with the oem gaskets from Subaru is that they are so expensive. Well Grimmspeed has your answer, a premium multi-layer steel w/ stainless steel fire-ring gasket at a great price.
