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.
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.
- OE-Specific Mounting — Application-specific mounting points for fan shrouds, inlet/outlet hoses, and top/bottom pins ensure a pain-free, no-modification install.
- Hand-Crafted Heliarc Welds — Each radiator is individually Heliarc welded by hand, creating the strongest possible aluminium-to-aluminium bond across all components.
