This brand new application features Koyorad's 25mm Hyper Core to maximize heat transfer. Koyo designs and manufactures each radiator with precision; therefore this is a direct-fit performance replacement for the stock OE plastic/aluminum radiator and bolts directly to the factory fan shroud for a quick and simple installation. They have also integrated a 1/8” NPT female accessory fitting (supplied with a threaded plug) to accept temperature sensors typically included with aftermarket temperature gauges.
