Oil Cooler Inlet Duct – Mitsubishi Evolution 6 & TME (MR463801 or MR533179 Replacement)

Restore function and improve airflow with this upgraded replacement oil cooler inlet duct for the Mitsubishi Evolution 6 GSR, RS, and the Tommi Mäkinen Edition. Designed as a direct-fit replacement for the discontinued OEM part MR463801 (Evo 6) or MR533179 (TME), this duct modernizes the original design while retaining factory fitment.

The Speedin Engineering duct replaces the failure-prone, rusted factory mounting brackets with a durable, corrosion-resistant solution and refines the internal geometry to smooth airflow toward the oil cooler. The result is improved airflow efficiency, better long-term durability, and a clean OEM+ installation, ideal for restorations or performance-focused builds.
