Koyo Half-Size Race Radiator – Mitsubishi Lancer Evolution VII / VIII / IX 4G63T MT 2001–2007
Application: Mitsubishi Lancer Evolution VII / VIII / IX | CT9A / CT9W | 4G63T | Manual Transmission | 2001–2007
Part Number: HH032412 (Koyorad / Coore)
The Lancer Evolution VII, VIII, and IX are among the most celebrated all-wheel-drive performance platforms ever built — WRC-derived machines powered by the legendary turbocharged 4G63T. For serious track and race builds where space is at a premium, Koyorad's HH032412 half-size race radiator offers a compact, high-performance cooling solution engineered specifically for the CT9A/CT9W platform.
At roughly half the width of a standard radiator, the HH032412 is designed for drag, small track, and short duration race builds where intercooler placement, turbo piping, or custom front-end configurations demand a narrower core. Nocolok furnace brazed, precision TIG welded by hand, and triple pressure tested — it delivers serious cooling performance in a compact package.
Why Koyorad?
- Precise Tube & Fin Alignment — Strict quality control ensures optimal coolant flow and maximum heat transfer efficiency across the entire core.
- Nocolok Furnace Brazing — All tubes, fins, headers, and brackets are bonded in a state-of-the-art Nocolok furnace, creating a structure that resists vibration, road debris, and the elements.
- Billet Filler Neck — Precision-machined billet filler necks are fitted to every unit for superior strength, durability, and a reliable seal.
- Compact Race Design — Half-size core allows for flexible front-end packaging in race and time attack builds where space is critical.
- Hand-Crafted Heliarc Welds — Each radiator is individually Heliarc welded by hand, creating the strongest possible aluminium-to-aluminium bond across all components.
