Cometic BMW 1990cc 86-92 94.5mm .070 inch MLS-5 Head Gasket S14B20/B23 Engine

If you're rebuilding the top end of your 1988-1991 BMW M3, a reliable head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of the S14B20 or S14B23 engine, ensuring a strong seal between your cylinder head and block.

Cometic's MLS design uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle high temperatures and harsh sealing environments, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron block configurations. The center layer is stainless steel and can be varied in thickness; this particular gasket has a compressed operating thickness of 0.070 inches and a 94.5mm bore, designed to match your engine's specifications precisely. These gaskets are designed to seal effectively without the need for additional sealants.
