Product Details

If you're rebuilding the top end of your BMW M20 engine, especially if you're adding forced induction, a strong head gasket is crucial. This multi-layer steel (MLS) gasket from Wiseco is built to handle the increased cylinder pressures and temperatures that come with power-adder applications. It's designed to maintain a solid seal between the aluminum cylinder head and the iron engine block, even under extreme conditions.

The gasket features internal embossments that expand with heat, creating an even tighter seal as the engine warms up and under high combustion loads. This well-built, 5-layer steel construction is made to withstand the high sheer forces common in these demanding setups. It has an 85mm bore and a .070 inch thickness, making it suitable for a range of M20 engine builds.

This gasket fits a variety of BMW models from the mid-80s to early 90s, including popular choices like the 325i and 525i. Ensure you have the correct gasket for your specific engine build to maintain reliable compression and prevent leaks.
