The Cometic MLX head gasket for Subaru FB25B is a .032" thickness, 95.5mm bore left‑hand side cylinder head gasket featuring an integrated "stopper" layer for combustion chamber sealing. The MLX construction improves clamp load around the cylinder without increasing bore distortion, providing a model‑specific replacement for the FB25B left‑hand bank where enhanced sealing is desired.
