Cometic GM LHU/LNF Gen-2 ECOTEC .042in MLX Cylinder Head Gasket - 88mm Bore

Cometic Gasket is known for making well-built sealing components, and this MLX cylinder head gasket is a solid option for your 2011-2013 Buick Regal with the LHU or LNF Gen-2 ECOTEC engine. This gasket is designed with an 88mm bore and a .042 inch thickness, which is crucial for maintaining proper compression and preventing leaks between the cylinder head and the engine block.

The HP shim technology built into this gasket is notable because it increases the clamping force around the combustion chamber. This is especially helpful for open deck blocks, as it helps ensure a strong seal even under demanding conditions. The outer layers of the gasket are embossed and coated with Viton, a material known for its resistance to heat and oil, further enhancing its sealing capabilities and durability.
