Cometic 16-17 Ford Focus RS 2.3L EcoBoost 89mm Bore .040in MLX Head Gasket Cometic Gasket C15294-040

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.
