GrimmSpeed does it again with 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 Intake 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!).
Note: These gaskets work great as a cost-effective OE-replacement, with or without TGV porting.
Came in on time. Quality is great fits perfect. Most definitely recommend

These worked perfectly

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.

Great product and fits perfect. Didn't have a problem with this product. Also good quality and great for tgv deletes.

bigger is better
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

fit spot on
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.

perfect fit went along great with my ported TGV's. That along with quick ship and a high quality product A + +
