Cometic BMW 135i/335i/X6/Z4 N54B30 85mm Bore .044in MLX Head Gasket - C15257-044Find parts that fit my vehicle

COMETIC MLX (Multi-Layer Stopper) gaskets utilize an integrated stopper layer for combustion chamber sealing and improved clamp load around the cylinder without increasing bore distortion. MLX technology can be found in some head gaskets and are made from the same materials as our MLS Head Gaskets. No sealants or re-torque required.

Whether its for a full rebuild or some standard maintenance, the proper engine components are needed to make sure your vehicle is running smooth.

Head Gaskets sit between the engine block and cylinder head. They prevent the mixture of any gasses and oils with the cooling system of your car. If the head gasket goes bad on your vehicle, it could cause extreme amounts of damage. If you're going to increase the amount of horsepower in your car, we recommend making sure your head gasket is in good condition.

All Cometic products are made in the United States with materials manufactured on American soil.
