Koyo Performance Radiator – Mazda 3 / Axela BK 2003–2009 & Ford Focus XR5 Turbo 2006–2011 MT
Application: Mazda 3 / Axela BK (2003–2009) & Ford Focus XR5 Turbo LS/LT/LV (2006–2011) | 2.3L Aspirated & 2.5L Turbo Petrol FWD | Manual Transmission Only
Part Number: KH061816 / KS061816 / KHXR5ST
The BK Mazda 3 is a sharp, driver-focused platform — and the MPS variant takes that further with a 190kW turbocharged 2.3L that puts serious heat through the cooling system. The Ford Focus XR5 Turbo shares the same platform DNA, with a 166kW 2.5L five-cylinder turbo that demands equally capable cooling.
Koyorad's all-aluminium replacement is a direct bolt-in upgrade for both applications, engineered to the same factory fit and mounting points as the OE unit. Nocolok brazed, precision TIG welded by hand, and triple pressure tested — it retains all OEM fan shroud mounts and stock hose connections with no modifications required.
