CSF's all-aluminum performance radiator is a direct drop-in for the Acura RSX Base and Type-S, adding cooling capacity for high-horsepower street and track builds. It uses a 2-row 42mm core with CSF's B-tube technology, brazing a B-shaped tube to raise heat-transfer surface area roughly 15% over standard oval tubes for dual laminar flow. Multi-louvered fins with a 6.5mm fin height maximize airflow, and the radiator accepts all factory quick-connect hoses, AC condenser, brackets and fan shroud with no modifications. It includes CNC-machined fittings, an all-aluminum race-style drain plug and a hand-polished mirror finish.
