Cometic Gasket BMW S14B20/S14B23 .036in MLS Cylinder Head Gasket - 94.5mm Bore

If you're rebuilding the top end of your 1988-1999 BMW M3 with an S14B20 or S14B23 engine, a reliable head gasket is crucial. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these performance engines, ensuring a strong seal between your cylinder head and block.

Cometic's MLS design 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 conditions and different surface finishes, meaning you won't need extra sealants. The center layer is stainless steel and can be varied to achieve different thicknesses, like the 0.036 inches this gasket offers, with a 94.5mm bore diameter that matches your engine's specifications.

This gasket is a well-built option for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks, as it can manage the shearing forces that can occur between dissimilar metals. It's a solid choice for ensuring your engine's compression stays where it belongs.
