Cometic BMW 1990cc 86-92 93.4mm .120 inch MLS Head Gasket S14B20/B23 Engine

If you're working on the S14B20 or S14B23 engine in your 1988-1991 BMW M3, this Multi-Layer Steel (MLS) head gasket from Cometic is a solid choice for sealing your cylinder head. It's designed to handle the demands of high-output engines, ensuring a reliable seal between your aluminum heads and block, or aluminum heads and cast iron blocks.

This gasket is built with 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 temperatures up to 482 degrees Fahrenheit, making it suitable for harsh sealing environments. The center layer is stainless steel and can be varied in thickness to meet specific requirements; in this case, it's set to a compressed thickness of 0.120 inches with a 93.4mm bore, perfect for the specified BMW engines. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying installation.
