Koyo Polished Aluminum High Performance Radiators

240SX Koyo Radiators

240SX Koyo Radiators Koyo high performance radiators are a definite must if you have turbocharged your KA or you are running an SR20DET. Stock Nissan Radiators are good, but plug up over time, and were only engineered to cool a stock powered engine. High compression and turbo motors create more power, but also create more heat (heat is a function of power), so you need to shed that extra water temperature so that you do not overcook your motor and damage it. Koyo rads are fully polished to a mirror-like finish, and increase the cooling capacity from 20-30% more than a brand new OEM radiator.

(if your radiator is over 12 years old, chances are corrosion, soot and buildup have diminished the OEM cooling of that radiator even more)

Manufactured from aircraft quality aluminum, all Koyo rads are heli-arc tig welded before being polished. All internals are Nocolok brazed. Backed with over 30 years of Japanese Domestic Market experience, Koyo radiators are engineered, designed and built for each individual application. No “universal” parts are used
