Radiators, Intercoolers, Oil Coolers & Coolant Reservoirs

Koyo

Koyo builds all-aluminum cooling parts for street and track cars. What we carry covers direct-fit all-aluminum radiators, including N-FLO triple pass and Hyper Core designs, HyperCore intercooler cores, row-count oil coolers with AN-10 ORB provisions, aluminum filler necks and expansion tanks, coolant reservoir adapters, radiator caps and radiator drain plugs. Most radiators are cut for one vehicle and year range, and those products name the vehicles they fit along with the transmission and engine they were built for. Intercooler cores, oil coolers, caps and drain plugs are sold by size instead, so check the core dimensions, port sizes and pressure rating listed in the specifications before you order.
