Part Number: HH020879 / KH020879

The R34 GT-R is the pinnacle of the Skyline GT-R lineage — the most refined, the most capable, and the most sought-after of the series. The RB26DETT twin-turbo inline-six is a legendary engine that responds exceptionally well to modification, and at elevated power levels the cooling system becomes a critical component. Whether you're running stock boost or pushing serious power, keeping coolant temperatures in check is non-negotiable.

Koyorad's all-aluminium radiator is a direct bolt-in performance upgrade for the BNR34, 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.
