Description

The leak stops here! Cometic MLX head gaskets feature a unique integrated "stopper" layer for optimum combustion chamber sealing and improved clamp load around the cylinder without increasing bore distortion. The MLX head gaskets, like their MLS counterparts, are multi-layer stainless steel for increased strength—and require no sealants or re-torquing. Dozens of models are available; order the MLX head gaskets designed to maximize your engine's power and performance.
