Cometic MLX Head Gasket Subaru WRX 08-14 WRX STI 07+ EJ255 EJ257 101mm Bore 0.040" Thick

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.
