LS1/LS6 Intake Manifold Gasket

The FEL-PRO LS1/LS6 Intake Manifold Gasket (Part No. 1312-3) is a precision-engineered composite gasket designed for General Motors LS-series engine platforms. This gasket is essential for sealing the intake manifold to the cylinder head during engine assembly, rebuilds, or gasket replacement operations.

Constructed from high-quality composite materials, this gasket is engineered to withstand the thermal cycling and pressure differentials typical in high-performance engine environments. With a thickness of 0.06 inches and cathedral-port geometry (1.19 x 3.34 inches), it is optimized for the airflow characteristics of LS1 and LS6 engines, ensuring reliable sealing surfaces and minimal compression losses.

Engine builders and technicians working with LS1 (5.7L, naturally aspirated) or LS6 (7.0L, naturally aspirated) powerplants will find this gasket set to be an industry-standard choice for intake gasket replacement. While it is suitable for stock applications, those with modified engines should verify compatibility with their specific intake manifold designs.
