Int Manifold Gasket Set 97-16 Chevy LS

The Int Manifold Gasket Set 97-16 Chevy LS is a critical engine seal designed for the legendary LS-series platform that powers everything from street machines to high-performance builds. Built for model years 1997 through 2016, this gasket pair addresses one of the most common leak points in LS engine architecture—the intake manifold junction where cylinder head and plenum meet. Whether you're rebuilding an engine in your shop, addressing a chronic coolant weep, or completing an engine swap, intake manifold gaskets are non-negotiable for maintaining system integrity and preventing performance loss.

This gasket set is engineered for cathedral-port LS heads with plastic intake manifolds, the factory configuration found across Chevrolet's LS platform lineup. The pair design ensures symmetric sealing across both cylinder banks, eliminating the need for separate left and right component sourcing. Cathedral-port geometry demands precision fit; these gaskets feature shape-matched profiles to the intake manifold underside and head porting, creating a thermal-resistant seal that handles sustained operating temperatures and combustion pressures inherent to forced-induction and naturally aspirated applications alike. The plastic manifold compatibility—standard across production LS engines—means no aluminum rework or custom fabrication is required.

Technicians, engine builders, and DIY enthusiasts restoring 1997–2016 Chevrolet LS-equipped vehicles benefit most from this direct-fit solution. Installation is straightforward: remove the intake manifold assembly, clean all mating surfaces thoroughly to bare material, apply a thin bead of RTV sealant if manufacturer instructions specify, position the gasket pair, and torque the manifold bolts to factory specification in a cross pattern. Proper installation eliminates future coolant and oil seepage, restores peak flow efficiency through the intake tract, and prevents catastrophic coolant loss. This is essential maintenance for any LS engine—whether stock, modified, or transplanted into a non-GM platform.
