Cometic Gasket BMW S14B20/S14B23 .060in MLS Cylinder Head Gasket - 94.5mm Bore

If you're rebuilding the top end of your 1988-1999 BMW M3, this multi-layer steel (MLS) head gasket from Cometic Gasket is a solid option. It's specifically made for the S14B20 and S14B23 engines, featuring a 94.5mm bore and a compressed thickness of .060 inches. MLS gaskets are known for their strength and ability to seal well, even with different block and head materials like aluminum heads to cast iron blocks.

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 temperatures up to 482 degrees Fahrenheit. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .060 inch on this particular gasket. Because it's an MLS design, it doesn't require any additional sealants, making installation more straightforward.
