Cometic Gasket is the world leader in custom multi-layer steel head gaskets for performance and motorsport engines. From off-the-shelf MLS for popular platforms to bespoke gaskets for race-only builds, Cometic seals everything from Honda B-series to LSX.
Ensure maximum engine integrity with the Cometic Multi-Layer Steel (MLS) head gasket, specifically engineered for the BMW S54 3.2L engine. With an 87.5mm bore and a .040-inch compressed thickness, this gasket is the ideal choice for high-performance builds, providing a robust seal that prevents leaks under the high cylinder pressures found in the M3, Z3 M, and Z4 M platforms.
Cometic MLS gaskets are designed to handle the unique thermal expansion characteristics of the S54 engine, ensuring a consistent seal between the head and block. The Viton coating provides a superior micro-seal, filling surface imperfections and resisting temperatures up to 482°F. This makes it an essential upgrade for any engine rebuild, especially for those running increased compression or forced induction. By choosing Cometic, you are opting for the same technology used by top-tier racing teams to ensure reliability and peak performance on the track. Keep your BMW running at its best with premium components from GGCRACING.
