Honda Civic Si Performance Radiator - Mishimoto - Aluminum - 2012-2015. A direct-fit, all-aluminum upgrade built to keep K-series temperatures under control on the street and at the track.

With a fully TIG-welded aluminum core and end tanks, it replaces the factory plastic-tank unit that can fatigue under heat cycling. A 63% increase in core volume over OEM adds surface area and thermal capacity for steadier coolant temps during hard use. It installs without cutting and connects to stock hoses and mounts. The included high-pressure cap stabilizes system pressure, and the Mishimoto magnetic drain plug captures ferrous debris.
