What makes an MLS head gasket different from a standard one?

An MLS (Multi-Layer Steel) head gasket uses multiple layers of steel for increased strength and durability. This design, especially with internal embossments, helps create a more reliable seal under extreme heat and pressure compared to older composite gaskets.

Do I need any special tools to install this head gasket?

Installation of a cylinder head gasket typically requires specialized tools such as a torque wrench to ensure proper bolt tightening sequence and pressure. Refer to the manufacturer's installation instructions for specific tool and procedure requirements.

What does the .070 thickness and 5-layer construction mean for my engine?

The .070 inch thickness and 5-layer steel construction are specific design choices for this gasket. This thickness is optimized for the M20B20 engine, and the multi-layer design ensures it can handle the high combustion pressures and temperatures common in performance applications.

Product Details

If you're rebuilding the top end of your BMW M20 engine, a solid cylinder head gasket is crucial for a good seal. This MLS (Multi-Layer Steel) gasket from Wiseco is built to handle the demands of these engines, especially when you're adding more power. It's designed to work with both aluminum heads and iron blocks, which is common in many BMW applications.

What makes this gasket stand out is its high-pressure steel-laminate construction. It's made of five layers of steel, and internal embossments actually expand with heat. This creates an even tighter seal when the engine is under high combustion pressures and temperatures, conditions you'll often find in modified or performance-oriented M20 engines. This means you can expect a more reliable seal, even when pushing the engine harder.

This gasket fits a range of BMW models, including the 325 series from the mid-80s to early 90s, as well as the 525i and 528e. Make sure to check the fitment details to confirm it's the right part for your specific BMW.
