CSF Mitsubishi EVO 7/8/9 2003-2007 High-Performance Full-Size Radiator

The Mitsubishi Evo has always been genuinely close to CSF, and there's no arguing the Evo shares a special place among JDM legends. The 4G63 is capable of incredible power, and paired with Mitsubishi's AWD system, the Evo is a monster on and off the road, but that unique combination of AWD, high boost, and an iron block genuinely demands a lot from the cooling system. Many Evo 7, 8, and 9 owners have relied on CSF Radiators for years to keep their high-horsepower builds cool.

The full-size version uses a 2-row, 42mm dual core with CSF's exclusive B-Tube technology. Rather than a regular oval "O"-shaped tube, CSF uses a specially engineered tube shaped like a "B", carefully formed and brazed over the seam to seal. This increases the heat transfer surface area of the tubes by approximately 15% over regular tubes, delivering the efficiency of two smaller tubes versus one large tube within the same space, and allows CSF to use thinner, lighter aluminium with better cooling efficiency, since this design is actually stronger than normal welded "O"-shaped tubes. High-efficiency, multi-louvered fins are precisely aligned to maximise airflow through the core, with fin specifications carefully measured and wind-tunnel tested for this specific application. This is a true drop-in fit design requiring no modifications to install.

Why Choose This Radiator

• CSF's exclusive B-Tube core technology, approximately 15% more heat transfer than regular tubes
• Full-size or half-radiator options to suit your specific turbo setup
• CNC-machined, welded OE-style brackets for durable, precise fitment
• Half-radiator option shares the same race-proven core used across countless high-boost Evo builds
• 100% all-aluminium, TIG-welded construction for genuine long-term strength
• True drop-in fit, no modifications required

Compatibility

• Mitsubishi Lancer Evolution 7 (2001-2003, 4G63T)
• Mitsubishi Lancer Evolution 8 (2003-2005, 4G63T)
• Mitsubishi Lancer Evolution 9 (2005-2007, 4G63T)

Important: if you're running large turbos with forward-facing manifolds, confirm you need the slim radiator (#7075) rather than the full-size version, as clearance requirements differ significantly between the two setups.
