Product Details
If you're rebuilding the top end of your BMW M20 engine, a solid head gasket is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of performance engines, offering a strong seal between your aluminum or cast iron block and aluminum heads.
This gasket is constructed with multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material designed to seal effectively even in harsh conditions and on various surface finishes. The compressed thickness of this gasket is .086 inches, with an 85mm bore, making it suitable for M20B25 and M20B27 engines found in a range of BMW models like the 325i, 325e, and 525i. Because it's an MLS design, it doesn't require any additional sealants, simplifying installation.
This Cometic gasket is a well-built option for your BMW M20 rebuild, offering reliable sealing for both street and more demanding applications.
