Koyo Performance Radiator – Nissan 350Z / Fairlady Z Z33 VQ35DE MT 2002–2009
Application: Nissan 350Z / Fairlady Z | Z33 (CBA-HZ33 / CBA-Z33 / UA-HZ33 / UA-Z33) | VQ35DE 3.5L V6 Petrol RWD | Manual Transmission
Part Number: VH021568 / KV021568U06
The Z33 350Z / Fairlady Z is a proper sports car — a naturally aspirated 3.5L V6, rear-wheel drive, and a chassis that rewards committed driving. The VQ35DE is a strong, free-revving engine that responds well to modification, and keeping coolant temperatures stable is key to getting the most out of it, especially on track or in spirited canyon runs.
Koyorad's all-aluminium radiator is a direct bolt-in performance upgrade for the Z33, 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.
