Cometic's MLX multi‑layer steel head gasket for Subaru FA20D and Toyota 4U‑GSE (left‑side) combines multiple stainless steel layers with embossed outer faces coated in Viton to resist heat and corrosion. The MLX construction uses an integrated stopper layer for combustion sealing and is engineered to improve clamp load distribution while minimizing bore distortion in the specified 89.5mm, .052" application.
