The Cometic MLX head gasket for select Porsche 997.2 and 991 series engines is a multi-layer gasket that uses an integrated stopper layer to seal the combustion chamber. It offers improved clamp load around the cylinder to tighten sealing without increasing bore distortion, supporting reliable sealing in high-compression or rebuilt engines where precise head clamping is important.
