Cometic GSR Intake Manifold Gasket – B18C1 / GSR

Description

Cometic Intake Manifold Gasket – B18C1 / GSR

The Cometic C4674 intake manifold gasket is designed to provide a reliable seal between the intake manifold and cylinder head on Honda B18C1 (GSR) engines. Constructed from a high-quality composite gasket material, it offers excellent sealing characteristics for street and performance applications where consistent intake vacuum and proper airflow are critical.

Compared to aging OEM gaskets, this gasket helps prevent vacuum leaks caused by heat cycling, material shrinkage, or surface irregularities. It is well suited for stock and mildly modified engines, including those running aftermarket intake manifolds or port-matched components.

This gasket is a direct-fit replacement and installs using standard procedures without the need for sealants when mating surfaces are clean and in good condition.
