Supertech Mazda MZR 2.0/2.3L 90mm Bore 0.029in (0.75mm) Thick MLS Head Gasket

This is a Supertech Multi-Layer Steel (MLS) head gasket specifically for Mazda MZR 2.0L and 2.3L engines. It features a 90mm bore and a thickness of 0.029 inches (0.75mm), making it a direct replacement for stock gaskets or a choice for engine rebuilds where precise sealing is critical.

MLS head gaskets are well-built with multiple layers of stainless steel, often with a special coating, to provide a strong seal between the cylinder head and the engine block. This design helps prevent leaks of combustion gases, coolant, and oil, especially under the higher pressures and temperatures found in performance or rebuilt engines. The 0.029-inch thickness is a common specification that works well for many MZR engine applications, ensuring proper compression ratios when used as a direct replacement.

When rebuilding your MZR engine, using a well-made MLS head gasket like this one from Supertech is important for ensuring long-term reliability and proper engine function. Always ensure your cylinder head and block surfaces are clean and flat before installation, and follow the manufacturer's recommended torque sequence and specifications for best results.
