Koyorad's new 48mm “HH” Series radiator core features an ultra high fin density to maximize heat transfer. Koyo designs and manufactures each radiator with precision; therefore each one is a direct-fit performance replacement for the stock OE plastic/aluminum radiator for a quick and simple installation with no modifications. Koyo has also integrated a 1/8” NPT female accessory fitting (supplied with a threaded plug) to accept temperature sensors typically included with aftermarket temperature gauges.
