Product Description

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.

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 upgrading to a cometic head gasket.
