The Cometic MLX head gasket for Subaru EJ255 (Version 2) and EJ257 turbo engines is a multi-layer stopper-style gasket with a 0.032" compressed thickness and a 101mm bore. MLX design uses an integrated stopper layer for combustion sealing and improved clamp load around the cylinder without increasing bore distortion. No sealants or re-torque are required per the product description.
