Koyorad proudly presents the HH Series Aluminum Racing Radiator, featuring a cutting-edge 48mm "HH" Series radiator core with an ultra-high fin density to optimize heat transfer. Koyorad's commitment to precision design and manufacturing ensures that each radiator serves as a direct-fit performance replacement for stock OE plastic/aluminum radiators. This guarantees a hassle-free installation without the need for modifications. Additionally, Koyorad has incorporated a 1/8” NPT female accessory fitting, complete with a threaded plug, to accommodate temperature sensors commonly used with aftermarket temperature gauges.

The HH Series radiator introduces Koyorad's innovative N-Flo Technology, which capitalizes on factory-equipped radiators with inlet and outlet locations that enable proper placement. By expertly welding aluminum partitions in the upper and lower tanks of the radiator, Koyorad has created the foundation for a double or triple pass radiator. This groundbreaking design enhances cooling efficiency by prolonging the coolant's stay in the radiator, resulting in superior heat transfer to the surrounding air.
