Cometic BMW 1990cc 86-92 94.5mm .095 inch MLS Head Gasket S14B20/B23 Engine

If you're rebuilding the top end of your 1988-1991 BMW M3, a solid head gasket is crucial for keeping that S14B20 or S14B23 engine running right. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines, ensuring a strong seal between your cylinder head and engine block.

This gasket 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 tough sealing environments and various surface finishes. The compressed operating thickness is .095 inches, and it's designed for a 94.5mm bore, fitting your specific M3 engine. Because it's an MLS design, it doesn't require any additional sealants, making installation more straightforward.

This type of gasket is well-suited for applications using aluminum heads with either aluminum or cast iron blocks, as it can manage the shearing forces that can occur between different metals. It's a well-built component designed for reliable performance in your BMW M3.
