Pontiac Intake Gasket

The Pontiac Intake Gasket by Mr. Gasket (MPN 502G) is a precision composite seal engineered for Pontiac V8 engines requiring reliable intake manifold sealing. This gasket addresses a critical maintenance need: preventing coolant and fuel mixture leaks that compromise engine efficiency and longevity. Whether you're performing routine intake manifold replacement, upgrading to performance heads, or restoring a classic Pontiac V8, this gasket delivers the dependable seal that separates top-tier builds from problem-prone installations.

Constructed from composite material and measuring 0.06 inches thick, the Pontiac Intake Gasket conforms precisely to rectangular ports measuring 1.14 by 2.06 inches—the OEM specification for most Pontiac V8 applications. The composite construction resists thermal cycling, chemical degradation from coolant additives, and compression creep better than paper or cork alternatives. At just 0.26 pounds, this gasket kit ensures minimal mass while maintaining the structural integrity needed to handle peak combustion pressures and maintain a water-tight seal across the full temperature range of street or track operation.

Mechanics and engine builders restoring or modifying Pontiac V8s—from 389 to 455 cubic-inch displacement engines—depend on this gasket to prevent the slow weep failures that become expensive diagnostic headaches. Installation requires proper torque sequencing and surface prep; cleaning mating surfaces to bare metal and applying a thin bead of gasket sealant ensures optimal sealing. This kit is essential for intake manifold removal, cylinder head work, or any build where coolant integrity cannot be compromised. Choose the proven composite gasket that fits factory tolerances and handles the demands of performance Pontiac engines.
