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

The B-Tube technology in this CSF radiator is a notable design choice. Unlike standard oval tubes, these specially formed tubes are seam-brazed, increasing the heat transfer surface area by about 15% over typical designs. This means you get the cooling efficiency of two smaller tubes in the space of one, allowing for a dual liquid laminar flow that helps keep your 2003-2006 Mitsubishi Lancer's engine cool, whether you're on the street or the track.

This radiator is built with a 2-row, 42mm core and uses ultra-efficient, multi-louvered fins that are precisely aligned to maximize airflow. CSF has over 50 years of experience, and they test their fin specifications in wind tunnels to ensure maximum heat rejection. The OE-style brackets are CNC machined for durability, and the inlet/outlet connections are designed to match the factory setup, meaning you can reuse your OEM hoses. It's a true drop-in fit, so no modifications are needed for installation, and it accepts all attaching OEM components like the AC condenser and fan shroud.

This all-aluminum radiator comes in a stealthy black finish and includes a 12-inch fan and shroud assembly, along with -16AN fittings for custom setups. It’s a solid option for high-horsepower builds or any Evo owner looking for improved cooling performance.
