Cometic Toyota B58/B58H .052in MLX Cylinder Head Gasket - 83mm Bore

This is the Cometic MLX cylinder head gasket, specifically made for Toyota B58 and B58H engines with an 83mm bore. It's built with a thickness of .052 inches, which is a common specification for these performance-oriented engines. This gasket is designed to create a solid seal between your engine block and cylinder head, which is crucial for maintaining compression and preventing coolant and oil leaks.

Cometic uses advanced multi-layer steel (MLS) construction for these gaskets. This means it's made from several layers of steel, each with a special coating. This multi-layer design allows the gasket to handle the high pressures and temperatures found in modern performance engines, offering improved sealing performance over older gasket types. The 83mm bore size is specific to the engine application, ensuring it matches the cylinder bore precisely for optimal performance and sealing.

This gasket fits a range of vehicles, including the Toyota GR Supra and various BMW models like the 540i and M340i. When you're rebuilding or repairing the top end of your engine, a well-made head gasket like this one is essential for long-term reliability.
