Application: Nissan Skyline GT-R | GF-BNR34 (2D Coupe) | RB26DETT 2.6L Twin Turbo Petrol AWD | Manual Transmission
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.
