Product Details

This Cometic Multi-Layer Steel (MLS) head gasket features a .027 inch compressed thickness, designed specifically for BMW M50B25 and M52B28 engines. It's built with multiple layers of stainless steel, giving it increased strength and the ability to rebound, which helps resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing conditions and various surface finishes, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron block setups. This well-built gasket requires no additional sealants, simplifying installation and ensuring a solid seal for high-output applications.

The center layer is uncoated stainless steel, allowing for precise thickness control, and in this case, it's set at .027 inches for optimal performance in engines like the BMW 323i, 325i, 525i, 328i, and 528i. The embossed outer layers and Viton coating work together to provide maximum sealing performance, even under demanding load conditions. This gasket is a solid option for rebuilding or repairing your BMW's engine, offering durability and reliable sealing.
