GrimmSpeed™ does it again! Introducting our 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 Int. Manifold going into the inlet of the TGV during porting. With our enlarged port gasket 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(right before it goes into the engine!).>

Pick up a couple pairs of these to match up with your GrimmSpeed™ Phenolic Spacers and/or GrimmSpeed™ TGV Deletes.

Better than OEM

side by side, yes there's a larger inner diameter. I also noticed my OEM gaskets to be a little tattered, or rough on the edges from being in the air stream. They are metal with rubber so the rubber was more affected but still... Also make sure to torque intake bolts to 6 ft lb, not 18. If you read the manual wrong, you're gonna have a bad time. I stretched a few bolts and broke one.
