LS1-LS6 Performance Intake Gasket .120in

The LS1-LS6 Performance Intake Gasket .120in by Fel-Pro is a critical sealing component designed for high-performance LS-platform engines that require precise airflow management. This gasket is ideal for builders working on street machines, race applications, or restoring vehicles like Corvettes, Camaros, or GTOs equipped with LS powerplants.

Engineered to withstand extreme combustion pressures and temperature fluctuations, this gasket features a .120-inch thickness that matches LS1 and LS6 intake manifold deck heights. Fel-Pro utilizes advanced elastomer compounds and reinforced facing materials that resist fuel vapor permeation, oil absorption, and thermal degradation, making it suitable for applications where manifold temperatures can exceed 180°F.

This gasket is essential for anyone building LS1 and LS6 engines, whether installing a stock intake manifold or upgrading to a performance casting. Its engineered sealing surfaces conform to minor surface irregularities, ensuring a reliable seal that prevents intake and vacuum leaks, which can negatively impact engine efficiency.
