Mazda MX-5 Miata Racing Radiator - Koyo - All Aluminum - `99-`05 (Koyorad VH060650) is a direct-fit replacement for 1999–2005 MX-5 Miata 1.8L manual transmission cars. This all-aluminum racing radiator is intended for drivers who need a more robust cooling solution for spirited driving and track use.

Built by Koyorad, the VH060650 racing radiator swaps into the Miata's factory mounting points for a bolt-in installation on manual-transmission 1.8L models. Its all-aluminum construction and performance-oriented core are designed to handle higher thermal loads than many stock units, helping maintain more consistent coolant temperatures during extended high-load operation. This unit is suitable for enthusiasts planning track days, autocross, or heavy street use who want a reliable upgrade without modifying the engine bay.
