Koyo Performance Radiator – Mazda 3 / Axela BL MPS 2.3L Turbo MT 2009–2014
Application: Mazda 3 / Axela | BL (4D Hatch) | L3VDT 2.3L Turbo Petrol FWD | Manual Transmission Only
Part Number: KH062306 / KS062306
The BL Mazda 3 MPS is the hot hatch that punches well above its class — 190kW of turbocharged 2.3L through the front wheels, wrapped in a practical hatchback body. That kind of power generates serious heat, and the factory cooling system is one area where a quality upgrade makes a real difference, especially on track or in spirited driving conditions.
Koyorad's all-aluminium replacement is a direct bolt-in upgrade, 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.
