Product Details
This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring an 85mm bore and a compressed thickness of 0.075 inches. It's designed to handle the demands of high-output engines, making it a solid choice for BMW M20B25 and M20B27 engines found in models like the 325i and 525i.
The outer layers of this gasket are coated with Viton, a heat-resistant rubber material that can withstand temperatures up to 482°F (250°C). This coating, combined with the inherent strength of the stainless steel layers, ensures a reliable seal between aluminum heads and either aluminum or cast iron blocks, resisting the shearing forces that can occur between different metals. Because it's an MLS design, it doesn't require any additional sealants, simplifying installation.
The center layer is uncoated stainless steel, and Cometic varies this layer to achieve different gasket thicknesses, allowing for precise engine builds. This well-built gasket offers improved strength and corrosion resistance due to its multi-layer stainless steel construction.
