Supertech BMW N54 86mm Bore 0.059in (1.5mm) Thick Cooper Ring Head Gasket

This Supertech head gasket uses a 1.5mm thick copper ring, a solid choice for rebuilding or modifying your BMW N54 engine. The copper ring is designed to provide a strong seal, especially important when dealing with the higher cylinder pressures that can come with performance tuning or when replacing a failed gasket.

Built to the exact 86mm bore specification for the N54 engine, this gasket ensures a precise fit. The copper ring is a notable feature that helps create a more robust seal compared to standard multi-layer steel (MLS) gaskets, particularly around the combustion chamber where heat and pressure are most intense. This can help prevent leaks and maintain consistent engine performance.

When you're working on your N54, using a well-built head gasket like this one from Supertech is key to a reliable rebuild. Make sure to follow the manufacturer's installation instructions carefully, as proper torque sequences and procedures are critical for achieving the best seal with this type of gasket.
