CSF 96-07 Mitsubishi Evo 4/5/6/7/8/9 Full-Slim Radiator w/12in Fan & Shroud/-16AN & Slip On Fitting

If you're pushing your 2003-2006 Mitsubishi Lancer hard, whether on the street or the track, keeping your engine cool is critical. This all-aluminum radiator from CSF is built to handle the extra heat generated by higher horsepower builds and demanding motorsports use.

CSF has been making radiators for over 50 years, and this one uses their exclusive B-Tube technology. Instead of a standard oval tube, these B-tubes are shaped and brazed to increase the heat transfer surface area by about 15% compared to regular tubes. This means more efficient cooling in the same space. They also use multi-louvered fins that are carefully aligned to maximize airflow and heat rejection, all tested in their wind tunnel lab to ensure top performance.

This radiator is designed as a true drop-in fit, meaning you won't need to modify anything to install it. It accepts all the original mounting hardware, including the AC condenser and fan shroud. The inlet and outlet connections are made to match the factory setup, so you can reuse your stock or aftermarket hoses. It also comes with a 12-inch fan and shroud assembly, making it a complete cooling solution right out of the box.
