Koyorad is proud to introduce all-aluminum remote radiators for the 2020 Toyota Supra and 2018 to current BMW Z4 3.0L.  Features include: hand welded end tanks, furnace brazed and high density 48mm Hyper cores, and split directional louvered fins.  Radiator core thickness has been increased by nearly 80% over the OEM auxiliary radiators to boost the platform’s heat capacity and endurance.  An all-aluminum construction provides an excellent upgrade to the OEM plastic tank heat exchangers which are prone to cracking over time.  Packaging includes both driver and passenger side remote radiators.  All mounting provisions are retained for the OEM rock guards and shrouding.  The OEM quick connect hoses are a direct fit allowing an easy 30 minute installation per side with common hand tools.  Advanced engineering and design methods, impeccable TIG welds, proficient furnace brazing, and triple pressure testing for quality has earned Koyorad an excellent reputation in performance cooling worldwide.

We have added the 2009-2014 Honda Fit (manual transmission) to Koyorad Part# KS082409 (Honda CR-Z) radiator application.  The two innermost fan shroud mounts (located on the top tank) on the Fit may require slight modifications in order to secure to the radiator.  For a complete bolt-in installation, OEM or aftermarket CR-Z shrouds (no motors) can be purchased (Honda Part# 19015-RBJ-004 and 38615-RBJ-003), which will accept the OEM Honda Fit fan units and bolt directly to the radiator.  Not compatible with OEM cap. Use Koyorad SK-C13 or equivalent deep plunger style cap.
