Intake Seal Kit - 8pcs.

The Intake Seal Kit - 8pcs. by FAST ELECTRONICS is a precision gasket set engineered for LSX intake manifold installations, where reliable sealing between the manifold and cylinder head prevents coolant and oil leakage under boost and sustained rpm load. This eight-piece kit addresses the critical sealing requirements of high-performance and stock LSX applications, making it essential for engine builders, performance enthusiasts, and shops conducting manifold swaps, rebuilds, or maintenance on LS-platform vehicles. Proper intake gasket sealing directly impacts cooling efficiency, oil circulation, and overall engine reliability.

Each seal in this kit measures 1.441 x 3.7 inches and is engineered as a rectangular port gasket in durable rubber construction, designed to handle the thermal cycling and pressure differential inherent to LSX intake manifolds. The rubber compound resists fuel, oil, and coolant exposure while maintaining compression set over repeated heat cycles, preventing creep that leads to weeping leaks around port boundaries. The eight-piece configuration ensures full coverage across multiple intake manifold designs and allows for replacement of worn or damaged seals during engine service or manifold repositioning without requiring a complete overhaul kit.

This kit is ideal for LS engine builders transitioning between naturally aspirated and boosted configurations, as well as technicians restoring high-mileage LSX platforms where original gaskets have degraded. Installation requires standard gasket removal, surface prep, and proper torque sequence to ensure even clamping load across all seal positions. Compatibility spans LS1, LS2, LS3, LS6, LS7, and LSX variants that accept F.A.S.T. intake manifolds, making it a core consumable for any shop specializing in LS-family engine work or street and track builds.
