Koyo Performance Radiator – Mazda 6 MPS GG MT
Application: Mazda 6 MPS | GG Chassis | Manual Transmission
Part Number: KV062779 | VH062779
The Mazda 6 MPS is one of the most underrated performance sedans of its era — a turbocharged, all-wheel-drive machine that punches well above its weight. When you're pushing the MPS hard, the factory cooling system can become a limiting factor under sustained high-load conditions. The Koyorad KV062779 is a direct bolt-in performance upgrade engineered for the GG Mazda 6, delivering improved cooling capacity without any cutting, drilling, or fabrication.
Koyorad's all-aluminium construction and high-efficiency 36mm core design dissipate heat faster and more effectively than the factory unit, keeping coolant temperatures in check even under sustained high-load driving. Nocolok furnace 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.
