Supertech Mitsubishi 4B11 87.5mm Bore .040in (1mm) Thick MLS Head Gasket

This Multi-Layer Steel (MLS) head gasket from Supertech is built to precise specifications for the Mitsubishi 4B11 engine, featuring an 87.5mm bore and a 1mm thickness. MLS gaskets are known for their ability to handle higher cylinder pressures and temperatures compared to traditional composite gaskets, making them a solid choice for rebuilds or performance applications where sealing integrity is critical.

The multi-layer construction uses stainless steel layers with specialized coatings to create a strong seal between the cylinder head and the engine block. This design helps prevent leaks and maintain consistent compression, especially important when you're working on the top end of your engine. The 1mm thickness is a specific dimension that needs to match your engine's requirements for proper compression ratio and valve-to-piston clearance.

When rebuilding or replacing your head gasket, ensuring you have the correct thickness and bore size is key to a successful engine assembly. This Supertech gasket is designed to fit the specified 4B11 engine, providing a reliable seal for your engine's critical combustion chamber.
