The CSF 2850K is an all-aluminum high-performance radiator built for K-series engine swaps in the 1992-2000 Honda Civic and 1994-2001 Acura Integra. It uses a 2-row 42mm dual core with CSF's B-Tube Technology, where seam-brazed B-shaped tubes add roughly 15 percent more heat-transfer surface area than standard oval tubes, paired with ultra-efficient multi-louvered 6.5mm fins. It is a drop-in fit with CNC-machined quick-connect inlet and outlet connections that accept OEM hoses, an all-aluminum race-style drain plug, and a hand-polished mirror finish.
