Koyo 88-91 Honda Civic / CRX EF Chassis w/B-Series (Manual Transmission) All-Aluminum Radiator

. Koyorad's revised version replaces the 53mm version with their new 36mm "Hyper V" core. While being a thinner core at 36mm, it is equally as effective because it was designed with a much higher fin density. This improved version saves weight, while improving space and air circulation to the engine and other components. Integrated into this new design is a female 1/8PT fitting (supplied with a threaded plug), which accepts temperature sensors typically included with aftermarket temperature gauges. This is a direct-fit performance replacement for the stock OE plastic/aluminum radiator for a quick and simple installation with no modifications. 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.
