Why upgrade

Keep your Z on the road and out of the shop with the Mishimoto Nissan 350Z Performance Aluminum Radiator! Every high-performance vehicle demands a cooling system that can maintain temperatures during both routine and competitive driving. These kits are engineered around real chassis packaging, so hoses, coolers and adapters line up without fabrication on the listed years. Follow the published torque specs and install guide, reuse sensors where instructed, and confirm clearances if you run other supporting mods. Every unit ships with the Mishimoto Lifetime Warranty for as long as you own it. Confirm hose routing, cooler clearance and sensor plugs before the first hard pull. US shipping dimensions and weight above are for the boxed kit. If fitment for a rare trim is unclear, call AutoTalent before ordering.
