CSF's all-aluminum triple-pass radiator is a direct drop-in for the manual-transmission Nissan 370Z and Infiniti G37/Q60, built to add cooling capacity for high-horsepower street and track builds. Its triple-pass flow structure routes coolant across the core three times before exiting for the lowest possible outlet temperatures, and the 2-row 42mm core uses CSF's B-tube technology to raise heat-transfer surface area roughly 15% over standard oval tubes. Multi-louvered fins with a 6.5mm fin height maximize airflow, and the kit includes both the radiator and AC condenser, accepting all factory quick-connect hoses, brackets and fan shroud with no modifications. CNC-machined fittings, an all-aluminum race-style drain plug and a satin finish complete it.
