Koyo Performance Radiator – Toyota GR Yaris GXPA16 G16E-GTS MT 2020+
Application: Toyota GR Yaris | 4BA-GXPA16 (3D Hatch) | G16E-GTS 1.6L Turbo Petrol AWD | Manual Transmission
Part Number: KH013831
The GR Yaris is one of the most exciting homologation specials in decades — a purpose-built rally-derived hot hatch with a 200kW 1.6L three-cylinder turbo, a bespoke AWD system, and a chassis that punches well above its class. The G16E-GTS is a highly stressed engine that generates serious heat, and with the GR Yaris increasingly popular on track and in rally events, cooling performance matters.
Koyorad's all-aluminium radiator is a direct bolt-in performance upgrade for the GXPA16, engineered to the same factory fit and mounting points as the OE unit. 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.
