Cometic 4B11T MLX Head Gasket β Engineered for Mitsubishi Evo X Performance
The Cometic MLX Head Gasket WC4483-044 is a premium performance cylinder head gasket designed specifically for Mitsubishi’s turbocharged 2.0-litre 4B11T engine, most notably used in the Mitsubishi Lancer Evolution X.
Performance engines generate significantly higher cylinder pressures and temperatures than standard road engines, making the cylinder-head sealing system particularly important. Cometic performance gaskets are developed to provide dependable sealing for demanding street, motorsport and modified-engine applications.
This version features an 88.00mm bore and .044-inch compressed thickness, making it suitable for compatible 4B11T engine builds requiring these dimensions.
Whether you are rebuilding a standard Evo X engine, upgrading the turbocharger, increasing boost pressure or assembling a dedicated high-performance 4B11T, the Cometic WC4483-044 provides a premium sealing solution from one of the best-known names in performance engine gaskets.

Why Choose a Cometic Head Gasket?
The cylinder head gasket is one of the most critical sealing components in a turbocharged engine. It must maintain an effective seal between the cylinder head and engine block while coping with combustion pressure, temperature fluctuations, coolant and engine oil.
Cometic has extensive experience producing sealing solutions for performance and motorsport engines. The C4483-044 / WC4483-044 is engineered specifically around the Mitsubishi 4B11T platform rather than being a generic universal gasket.
For tuned Evo X applications, selecting the correct gasket bore and compressed thickness is particularly important when rebuilding or modifying the engine.
