Features:
GrimmSpeed does it again with the Enlarged Bore Intake Manifold to TGV Gaskets. Why do you want the enlarged bore style vs. the small OEM? 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 during porting. With these enlarged port gaskets we are able to match the IM and TGV up perfectly which greatly improves air flow quality at a very important location in your intake track- that is right before it goes into the engine!
Pick up a couple pairs of these to match up with your GrimmSpeed Phenolic Spacers.

I have never used this quality of exhaust gaskets and by a mile these are better than any others including OEM. And as expected customer service was top notch. And when I accidentally ordered duplicate kits the return was as smooth as butter and got a full refund same day they received my return

One can never go wrong with Grimmspeed. High quality gasket. Does what it is intended to do. No air leaks. Installed on ‘18 STI.

Replacing the OEM TGV Gaskets with these is a grate choice, now that the bore is enlarged.

I used these gaskets recently in replacement of the factory metal Subaru gaskets that I normally use, an I am very pleased. They seem to seal very well and the fitment was perfect!
They got rid of the over hang in the TGV so these proved way better air flow
Would buy it every time I need it!
