Koyorad - Radiator HH Series HH031610 - 03-07 Mitsubishi EVO

The 48mm radiator core of Koyorad's "HH" Series has an extremely high fin density to optimize heat transfer. Every radiator is meticulously crafted and produced by Koyo, making it a perfect, direct-fit replacement for the original plastic/aluminum radiator. No modifications are necessary for installation. Koyo has even included a 1/8" NPT female accessory fitting (complete with a threaded plug) to accommodate additional temperature sensors commonly used with aftermarket temperature gauges. 

The superior quality of Koyorad radiators is a direct result of their privately owned factories, allowing Koyorad Japan to meticulously oversee every stage of production. This commitment to quality is evident in their hand-assembled, Nocolok brazed, and TIG welded all aluminum radiator cores, made with the highest quality aluminum. These are just a few of the exceptional features that have earned Koyorad radiators their renowned reputation for performance worldwide.
