Koyo leads the radiator industry in quality, performance, fitment, and extensive list of vehicle applications. Our quality begins with the careful testing in our RandD department, then to the manufacturing in Koyo s privately owned ISO 9001 certified factories, and finally to our class leading packaging. This process assures that each Koyo OE aftermarket replacement radiator arrives safely and performs perfectly in the hands of the shop and end user. Our engineers carefully design our radiators offering a true plug and play installation: No drilling, cutting, relocating, or stretching to get our radiators to fit properly. When you buy a Koyo radiator, you will receive a component that has been engineered to the highest standards. This is the version for Automatic Transmission that includes hook up for trans oil cooler but this can be installed in MT cars and the cooler can be used as an engine oil cooler if desired.
