The Intake Port Seals (8pk) for LSXr, LSXrt, LS1, LS6, and LS7 engines are precision rubber gaskets specifically designed for F.A.S.T. LSX intake manifold applications. Each pack contains eight seals that match the rectangular port geometry of these LS-platform architectures, ensuring a proper fit for optimal performance.
These seals form a critical interface between the intake manifold and cylinder head, effectively preventing vacuum leaks that can degrade fuel mixture control and idle stability. The rubber composition is engineered to maintain contact pressure across thermal cycles, which is essential for performance in environments where temperatures can fluctuate significantly.
Engine builders and tuners will find these seals invaluable during manifold upgrades, head gasket services, or modifications involving boost or nitrous systems. By ensuring a tight seal, these F.A.S.T.-specific seals help maintain fuel trim and idle quality, allowing for precise calibration without the interference of air leaks.
