DESCRIPTION

Koyo aluminum racing radiators are designed to be direct factory replacement units. Koyo racing radiator features a much thicker core with a more efficient fin design that helps with flow and temperature drop over the surface.

Koyo is Japans largest aftermarket radiator manufacturer, utilizing the latest aircraft quality aluminum and Heli-arc welded. Heli-arc soldering is the highest quality standard for enforcement along aluminum connections. The Koyo radiator is roughly 20mm thicker then stock, allowing for larger capacity, better flow, and faster heat loss over the surface of the core.

Koyo has also tapped the top of the radiator for a 1/8th PT fitting, allowing for installation of a water temp sensor. It comes fitted with a plug which can be removed for the sensor to be installed.

This radiator is only for cars with manual transmissions. It will not work on the automatic cars.

Upper radiator hose may require trimming for proper clearance

This is a great up grade to the stock plastic radiator. It's all aluminum and thicker, plus it looks great under the hood. Very easy to install. I'm happy with this radiator.

Great quality product and looks awesome in the engine bay. Easy to install. Only one installation problem - the hose connection that goes to the header tank is 1/2 inch on the Koyo and 1/4 inch on the OE radiator. I had to make an adapter and use some 1/2 hose to connect it up. Also, remember to tighten the drain plug in the Koyo as it is supplied loose. Very happy overall with this radiator.
