Koyo (Koyorad) Performance Radiator: Nissan 350Z / Fairlady Z Z33 VQ35HR MT 2007+

Koyo Performance Radiator – Nissan 350Z / Fairlady Z Z33 VQ35HR MT 2007+

Application: Nissan 350Z / Fairlady Z | CBA-HZ33 & CBZ-Z33 | VQ35HR 3.5L V6 Petrol RWD | Manual Transmission

Part Number: V2999 / KV022140R

The late-model Z33 350Z with the revised VQ35HR is the sharpest version of the platform — more power, better breathing, and a more refined driving experience than the earlier VQ35DE. Whether you're tracking it, canyon carving, or building for more power, keeping coolant temperatures stable is key to getting the most out of the VQ35HR.

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

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.
