This Cometic MLX cylinder head gasket for Subaru FA20 applications (2015–2019 WRX FA20DIT, left side) is a .032in multi‑layer steel gasket engineered for the application. MLX construction includes an integrated "stopper" layer to enhance combustion chamber sealing, and the design aims to improve clamp load around the cylinder without increasing bore distortion for reliable sealing in high‑duty engines.
