Cometic BMW M20 2.5L/2.7L 85mm .051 inch MLS Head Gasket 325i/525i

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s designed specifically for BMW M20 engines with a 2.5L or 2.7L displacement and an 85mm bore. This gasket is crucial for keeping your engine's combustion chambers sealed, preventing coolant and oil from mixing and ensuring proper compression.

This MLS 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), making it suitable for harsh sealing environments and various surface finishes. The center layer is uncoated stainless steel, allowing for precise thickness control. At a compressed operating thickness of .051 inches, this gasket is built to handle the demands of high-output engines and works well with both aluminum and cast iron blocks.

This head gasket fits a range of BMW models, including the 325i, 525i, and 325e. Because it's an MLS design, it doesn't require any additional sealants, simplifying installation. It's a solid option for anyone rebuilding the top end of their M20 engine.
