The Cometic MLX cylinder head gasket for BMW N54B30 is a .040in multi-layer design with an 85mm bore that increases clamp load around the combustion chamber via HP shim technology. MLX construction includes an integrated stopper layer to enhance combustion chamber sealing. Embossed outer layers coated with Viton and improved clamp distribution aim to bolster sealing without increasing bore distortion for high-compression or forced-induction engines.
