Fel‑Pro performance intake manifold gasket is a non‑metal‑core design that allows engine builders to trim the gasket for exact fit on modified ports. Tested across aftermarket head and manifold combinations, it’s intended for performance applications and is not for use in emission‑controlled vehicles. This gasket is optimized for custom fits where trimming and modification are required.
