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.
Comes in set of 2

This is a great gasket replacement if you are doing a Tgv delete, it is opened up a lot more then an oem gasket. The gasket itself is also thicker than a stock one. Definetly a great product

Grabbed some of these along with the PNP job and they fit spot on. Tried the OEM gaskets but noticed that some of the gasket sticks into the interior of the ports which would in turn cause turbulant air flow. With the GrimmSpeed gaskets, there is no interference with air flow.
