Cometic MLX Head Gasket 4.250" Bore for M-Eight Engines

Elevate your M-Eight engine's reliability and performance with the Cometic MLX Head Gasket, specifically designed with a 4.250" bore. This advanced multi-layer steel (MLS) gasket is engineered to withstand extreme conditions, ensuring a superior seal for demanding applications.

Description

The Cometic MLX (Multi-Layer-Xtreme) head gasket is the ultimate solution for M-Eight engines subjected to high-performance modifications, including turbocharging, high compression ratios, nitrous oxide systems, or any power-adding enhancements. Crafted from premium, fuel-resistant multi-layer steel (MLS), this gasket is engineered to prevent common failures like creeping, cracking, or becoming brittle under extreme operating temperatures and pressures. Its innovative MLX design incorporates an extra “stopper” fold-over layer, providing a crucial torque-limiting surface that effectively prevents yielding of the combustion seal. Proprietary high-temperature coatings, combined with precision embossments, create a micro-seal for fluids against both the head and block surfaces, ensuring leak-free operation. This robust 4.250" bore cylinder head gasket offers unparalleled durability and a long-term reliable seal, making it an essential upgrade for serious riders. Designed and proudly made in the USA, it reflects Cometic's commitment to quality and performance.
