Product Details

If you're rebuilding the top end of your Mitsubishi Lancer Evolution X, a solid head gasket is crucial for sealing the combustion chamber and coolant passages. This JE Pro Seal head gasket is built specifically for the 4B11T engine, ensuring a proper fit and reliable seal. It's designed to handle the pressures and temperatures common in performance applications, helping to keep your engine running smoothly.

This gasket features a multi-layer steel (MLS) construction, which is a popular choice for high-performance engines because it offers excellent sealing capabilities and can accommodate slight imperfections in the mating surfaces. The 87.5mm bore size is specific to the stock bore of the 4B11T engine, making it a direct replacement. JE Pistons is a well-known name in performance engine components, and this gasket is made to meet those standards.

When installing a head gasket, it's important to follow the manufacturer's torque sequence and specifications precisely. This ensures the gasket seals correctly and prevents leaks. Make sure your cylinder head and block surfaces are clean and flat before installation for the best results.
