GrimmSpeed Gasket Tumbler to Engine Subaru 2002-2014 WRX / 2002-2019 STI
DESCRIPTIONGrimmSpeed Tumbler to Engine Gaskets
GrimmSpeed offers an enlarged variation of the standard size OEM gasket. Why do you want the enlarged bore style vs. OEM style? The OEM gasket hole diameter is much smaller than the TGV itself so you are very limited on matching up the ports of the outlet of the intake manifold going into the inlet of the TGV. GrimmSpeed's gasket will not intrude into the flow path, restricting flow!
Note:Price is for 2 gaskets.
