Product Description

The Mishimoto MMFN-EVO-RD is a direct-fit aluminum coolant fill inlet designed to replace the factory plastic unit on the 2008-2015 Mitsubishi Lancer Evolution X. The OEM plastic inlet is a known weak point on the Evo X platform - repeated heat cycling from the turbocharged 4B11 engine causes the plastic to become brittle and crack over time, leading to coolant leaks and potential overheating. Mishimoto's all-aluminum replacement eliminates this failure point entirely, offering a durable, corrosion-resistant solution that outlasts the factory part.

The inlet is powder coated in red for a clean, high-quality finish that stands out in the engine bay and matches other red Mishimoto cooling components. It retains the factory hose routing and mounting positions for a bolt-on installation, and is tested for compatibility with both OEM coolant hoses and Mishimoto's silicone hose replacement kits. A replacement coolant fill cap is included. Backed by the Mishimoto Lifetime Warranty.
