Cometic BMW 318/Z3 89-98 85mm Bore .051 inch MLS Head Gasket M42/M44 Engine

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed stainless steel layers, featuring a heat-resistant Viton rubber coating on the outer layers. With a compressed operating thickness of 0.051 inches and an 85mm bore, it's specifically designed for the M42B18 and M44B19 engines found in your BMW 318i, 318is, 318ti, and Z3 models from the early 90s through the late 90s.

MLS gaskets are known for their strength and ability to handle high-output engines, offering excellent sealing performance without needing additional sealants. They work well with both aluminum and cast iron block combinations, and the stainless steel construction provides resistance to corrosion and shearing forces. The Viton coating on the outer layers is designed to withstand harsh sealing environments and high temperatures, up to 482 degrees Fahrenheit (250 C), ensuring a solid seal.

This gasket is a well-built option for rebuilding the top end of your M42 or M44 engine. It's important to ensure your cylinder head and block surfaces are clean and flat before installation for optimal performance.
