18 Deg Chevy Intake Gasket HIGH PORT .03in T

The 18 Deg Chevy Intake Gasket HIGH PORT .03in T by FEL-PRO is a precision composite gasket engineered for small-block Chevrolet engines equipped with 18-degree cylinder heads. This gasket seals the critical junction between the intake manifold and cylinder head, preventing coolant and oil cross-contamination that can degrade engine performance and longevity. Technicians and engine builders across law enforcement motor pools and military vehicle maintenance operations rely on OEM-equivalent gaskets like this to maintain seal integrity under sustained operational stress.

Manufactured to FEL-PRO specifications, this gasket features a .03-inch composite construction with a rectangular port design (1.25 x 2.15 inches) optimized for high-port intake configurations on small-block Chevy platforms. The material composition resists thermal cycling, fuel vapor permeation, and coolant degradation—critical properties in vehicles operating under extended idle, high-heat tactical environments, or prolonged field deployments. The precise 18-degree head angle ensures proper contact pressure distribution across the sealing surface, eliminating hot spots and micro-leaks that compromise engine efficiency and drivability.

This gasket is essential for anyone rebuilding or servicing small-block Chevy engines in vehicles requiring certified OEM-level reliability—utility trucks, command vehicles, and support rigs used in demanding field operations. Installation requires careful surface prep: both manifold and head surfaces must be clean and flat to specification. The lightweight design (0.21 lbs) facilitates quick replacement during routine intake servicing or full engine overhauls. Compatible exclusively with small-block Chevrolet engines featuring high-port intake manifolds and 18-degree cylinder head configurations.
