Cometic BMW M50B25/M52B28 Engine 85mm .140 inch MLS Head Gasket 323/325/525/328/528

Cometic Gasket is known for making well-built sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s designed specifically for BMW M50 and M52 series engines, including popular models like the 323i, 325i, 525i, 328is, and 528i, ensuring a proper fit for a range of BMWs from the early 90s to the turn of the millennium. This gasket plays a crucial role in keeping your engine's combustion chambers sealed, which is vital for maintaining compression and preventing coolant and oil from mixing.

This MLS gasket is constructed from multiple layers of stainless steel, giving it increased strength and the ability to rebound, which helps it resist corrosion and maintain its seal even under the stress of high-output engines. 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 with different block and head materials, including aluminum to cast iron. The center layer is uncoated stainless steel and can be varied to achieve different compressed thicknesses; in this case, it’s set to a .140 inch operating thickness, which is a common requirement for these BMW engines. Because it's an MLS design, it doesn't require any additional sealants, making installation more straightforward.
