• Backed by Cometic's reputation for precision-engineered gaskets tailored for motorsport and performance applications.

Construction & Design

The Cometic MLX gasket features a multi-layer steel (MLS) construction with an integrated stopper layer that provides a robust barrier against combustion pressure. The gasket's .044" thickness strikes a balance between providing a reliable seal and maintaining proper compression for high-performance engines. Its design ensures even distribution of clamping force, reducing the likelihood of head gasket leaks or warping during aggressive driving or tuning.

Manufactured using advanced stamping and laser-cutting techniques, the gasket maintains precise dimensions and consistent quality. The high-grade materials used resist corrosion and thermal expansion, ensuring long-term durability. The gasket's seamless integration with OEM and aftermarket cylinder heads makes it a trusted choice for rebuilds and performance upgrades alike.

Performance & Sound

While this gasket is primarily designed for sealing and durability, its high-quality construction helps maintain optimal compression and combustion efficiency. This results in improved engine responsiveness and consistent power delivery. The gasket's reliable sealing also prevents coolant and oil leaks, contributing to smoother engine operation and peace of mind during high-stress driving conditions.

Installation & Fitment

The Cometic MLX .044" Head Gasket is a direct bolt-on replacement for the factory gasket on the Mitsubishi Lancer Evolution X with the 4B11T engine. Its precise manufacturing ensures a perfect fit without the need for additional modifications. No sealants or re-torque procedures are required, simplifying installation and reducing downtime. It is recommended to follow standard head gasket replacement procedures, including proper cleaning of mating surfaces and torque specifications, to ensure optimal sealing and longevity.
