5150 AutoSport Head Gasket & Head Stud Kit, BMW / Toyota B58 Gen2
MLX Head Gasket The Cometic MLX Head Gasket is engineered for B58 turbocharged inline-six engines in BMW chassis and the Toyota GR Supra A90/A91. It replaces Toyota part # 11115WAA04 ,11127934583, and 11127934584. C14144-036, C14144-040, C14144-042, C14144-04052 Built with multiple layers of coated and uncoated stainless steel, MLX gaskets conform to the cylinder head and block during the first heat cycle, forming a chemical bond for superior sealing. The layered design acts as a spring, preventing blowouts and compensating for head lift. Note: MLX gaskets are not compatible with engines using O-rings or receiver grooves, as they require smooth surfaces for proper sealing.

Made from M0115 asbestos-free material, it features AISI 304 stainless steel Cooper Rings that bite into the aluminum head for maximum sealing, ideal for high-boost (2+ bar) applications with turbo or nitrous.
