Koyo 48mm Radiator for Nissan GT-R (R35)

Creating horsepower in an engine, creates heat. The heat needs to be transported away from the engine by the cooling system. An upgraded radiator allows for more heat to be transferred from the engine to the atmosphere. According to Koyo, this is the same radiator that the Cobb Tuning R35 GT-R uses in time attack. Check out the press release below.

Koyorad | Koyo is proud to introduce a direct replacement all aluminum performance radiator for the 2009-Current Nissan GT-R. This brand new application features Koyorad's new 48mm “HH” Series radiator core with an ultra high fin density 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 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.

Koyorad quality is a direct result of their privately owned factories which allow Koyorad Japan to oversee each stage of radiator production. This ensures that quality is never sacrificed for quantity. Each Koyo all aluminum radiator core is hand assembled, Nocolok brazed, then TIG welded by hand with the finest aluminum available. These are just a few characteristics that have earned Koyorad Radiators their excellent reputation in performance radiators worldwide.
