Intake Gasket Set - GM LS1/LS2/LS6

The MAHLE ORIGINAL Intake Gasket Set for GM LS1/LS2/LS6 engines is a critical sealing component engineered to prevent coolant and oil leakage at the intake manifold junction. This composite gasket set maintains compression integrity and thermal stability across the cathedral port design, essential for engines running sustained load or high-RPM applications where manifold gasket failure can result in coolant loss, overheating, and catastrophic engine damage.

Specifications for this intake gasket set include a 0.06-inch thickness and cathedral port dimensions of 1.15 x 3.375 inches, matching OEM tolerances for LS-series applications. The composite construction provides superior gasket life compared to traditional rubber, resisting thermal cycling and chemical attack from modern coolant formulations. Installers should note this is a paired set—quantity sufficient for both cylinder head ports—and replacement requires manifold removal and thorough surface preparation to achieve proper seal.

LS-series engine owners performing manifold service, coolant system upgrades, or addressing existing intake leaks depend on OEM-specification gaskets to avoid repeat failures. Whether rebuilding a performance street engine, maintaining fleet vehicles, or restoring vintage LS applications, this MAHLE ORIGINAL component delivers the sealing performance required for long-term reliability and engine longevity.

MAHLE remains the OEM gasket supplier for General Motors, meaning this intake gasket set matches factory specifications and material standards. Sourcing genuine MAHLE components eliminates variability introduced by aftermarket alternatives and ensures compatibility with your LS engine platform.
