Seal in Ultimate Power with Cometic MLX Technology

When you are pushing your GM LS engine to its absolute limits, standard head gaskets just won't cut it. The Cometic MLX (Multi-Layer Steel-X) Cylinder Head Gasket (Part # C15747-052) is engineered specifically to withstand the extreme cylinder pressures generated by high-horsepower, naturally aspirated, turbocharged, supercharged, or nitrous-fed LS Gen 3 and Gen 4 builds.

Featuring Cometic's innovative multi-layer design, this premium gasket integrates an extra fold-over stopper layer to create a robust mechanical seal around the combustion chamber. Say goodbye to combustion blow-by and hello to unyielding reliability.
