Product Details

CSF has been making radiators for over 50 years, so they know a thing or two about keeping engines cool. If you've got a 2003-2006 Mitsubishi Lancer Evolution 7, 8, or 9, especially one that's seen some track time or has a bit more power than stock, this all-aluminum radiator is a solid choice for improved cooling performance.

This radiator uses CSF's B-Tube Technology, which is a unique design that increases the heat transfer surface area by about 15% compared to standard oval tubes. This means it can dissipate heat more efficiently, helping to keep your engine temperatures in check. It also features multi-louvered fins that are precisely aligned to maximize airflow through the core, further boosting its cooling ability. The core itself is a 2-row, 42mm design, giving you plenty of capacity for heat exchange.

CSF designed this radiator to be a direct fit, meaning it bolts right into your Lancer without needing any modifications. It's built with CNC machined brackets and fittings for durability and a precise fit, and it's made to accept all your original mounting hardware, hoses, and even the AC condenser. It also includes a race-style drain plug for easy draining.
