The JZX90 Mark II, Chaser, and Cresta are among the most iconic JDM performance platforms ever produced — rear-wheel drive, turbocharged, and endlessly tuneable. The 1JZ-GTE is a legendary inline-six that thrives on boost, but sustained hard driving demands a cooling system that can keep pace. The Koyorad H010409 is a direct bolt-in performance upgrade engineered specifically for the JZX90 with manual transmission, delivering improved cooling capacity without any cutting, drilling, or fabrication.

Koyorad's all-aluminium construction and high-efficiency 48mm core design dissipate heat faster and more effectively than the factory unit, keeping coolant temperatures in check even under sustained high-load driving. 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.
