Construction & Design

The kit’s core component, the MLS head gasket, is constructed from multiple layers of high-grade steel. This design ensures a consistent and reliable seal between the cylinder head and engine block, even under high combustion pressures and temperature fluctuations. The use of aramid fiber and Armor Clad materials in other gaskets and seals enhances resistance to heat, oil, and coolant exposure, reducing the risk of leaks and premature failure.

Cometic’s engineering focuses on durability and precision fitment, which helps maintain engine integrity and performance over time. Each gasket is manufactured to meet or exceed OEM specifications, ensuring compatibility and ease of installation.
