90-95 LT5 Intake Plenum Gasket Set (3/64" Upgraded Size)

New reproduction 1990-1995 Corvette LT5 intake plenum gasket set. 3/64" Upgraded size gaskets (50% thicker). Sold in pairs.

Direct replacement on stock engines. Oversized gasket port size does not affect function or engine operating characteristics. Port size increased to 37.5mm for modified, ported intake. For Siamese porting, simply cut out the center bifurcation. Coolant flow for throttle body heat can be enabled or blocked by simply orienting the gasket as desired.

3/64" thick material is better suited for applications where mating surfaces may be less true or damaged by porting or welding; or damaged from improperly cleaning mating surfaces. Re-use of intake gaskets are not recommended, but because gasket materials are 50% thicker than the standard 1/32" gasket - it is more resistant to being damaged if the plenum is removed again.

Made from Pro-Formance/MicroPore, non-asbestos gasket material with a fully cured nitrile butadiene rubber binder, 12 20% compressibility for excellent seal ability and a max temp rating of 550F.

Note: See Zip # M-4249 for 1/32" thick gaskets.
