BMW N55 Head Gasket & Head Stud Kit
OEM Head Gasket (BMW N55) Genuine BMW head gasket for N55 engines (Part #11127599212). Proven reliable in high-horsepower and high-boost applications. For engines exceeding 800+ horsepower, O-ringing the cylinder head or block is required. Cometic MLX Head Gasket (BMW N55) A direct replacement for BMW part numbers 11127599212, 11127599213, 11127849620, and 11127849621, designed for N55B30 turbocharged inline-six engines. Constructed with multiple layers of embossed stainless steel, the MLX gasket conforms to the head and block during the first heat cycle, creating a secure seal. The specialized ‘stopper’ layer prevents combustion seal failure by providing a torque-limiting surface. Key Features: Improved sealing with proprietary coatings that create a micro-seal against fluids. Enhanced durability against blowouts with active spring-like layers. Not compatible with O-ringed or grooved engine blocks—requires smooth, flat surfaces. Installation Guidelines: Ensure all mating surfaces
