Cometic BMW M54 2.5L/2.8L 85mm Bore .092in MLS-5 Head Gasket

If you're rebuilding the top end of your BMW M54 engine, a reliable head gasket is crucial for proper sealing and preventing leaks. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these engines, whether you're dealing with aluminum heads on aluminum blocks or aluminum heads on cast iron blocks. It's designed to resist the shearing forces that can occur between different metals.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist 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 various sealing environments. The center layer is uncoated stainless steel, and its thickness can be varied to meet different requirements; in this case, it's set at a compressed thickness of 0.092 inches for an 85mm bore. This design means you don't need any additional sealants for installation.

This Cometic head gasket is a solid option for a range of BMW models, including the 325i, 525i, and Z4, among others. It's a well-made component that offers dependable sealing for your engine rebuild.
