Cometic BMW 1990cc 86-92 94.5mm .027 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 built with multiple layers of stainless steel for strength and corrosion resistance, which helps it handle the forces between aluminum and cast iron blocks. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing jobs and various surface finishes without needing extra sealants.

This gasket has a compressed thickness of 0.027 inches and a bore size of 94.5mm, specifically made for the 1990cc displacement of these S14 engines. The layered stainless steel construction gives it the strength to rebound and resist corrosion, making it a durable option for high-output engines. Because it's an MLS gasket with Viton coating, it's designed to seal effectively on its own, even with aluminum heads mated to either aluminum or cast iron blocks.
