Cometic BMW M54 2.5L/2.8L 85mm .036 inch MLS Head Gasket

If you're rebuilding the top end of your BMW M54 engine, a quality head gasket is crucial for a solid seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these engines, whether you're dealing with aluminum heads and blocks or a mix of aluminum and cast iron. It's designed to provide maximum sealing performance without needing any extra sealants, which makes installation a bit more straightforward.

Cometic constructs this gasket with 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 temperatures up to 482°F (250°C) and works well in tough sealing environments. The specific compressed thickness of this gasket is 0.036 inches, with an 85mm bore, making it a good fit for BMW 325Ci, 525i, and X5 models from the early to mid-2000s, among others. This construction helps it withstand the shearing forces that can occur between different metal types, ensuring a reliable seal.
