Cometic Gasket BMW S14B20/S14B23 .086in MLS Cylinder Head Gasket - 94.5mm Bore

If you're working on the S14B20 or S14B23 engine in your 1988-1999 BMW M3, this Multi-Layer Steel (MLS) cylinder head gasket from Cometic Gasket is built to handle the job. MLS head gaskets are a popular choice for performance engines because they offer excellent sealing without needing any additional sealants. This gasket features a 94.5mm bore and a compressed thickness of .086 inches, designed to fit your specific M3 application.

Cometic constructs these MLS gaskets from multiple layers of stainless steel, which gives them increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating is crucial for sealing effectively against various surface finishes and under demanding load conditions, making it suitable for both aluminum and cast iron blocks. The center layer is stainless steel and can be varied to achieve different thickness requirements, ensuring a precise fit for your engine build.
