OE Style Copper Core
Coated for anti corrosion
OE fitment and mounting
Koyo's "S" Sports Series Copper radiators feature OE style copper core brazed to powder coated end tanks for a show quality finish. Koyo uses state of the art Nocolok Brazing Furnace to bond all of the radiator brackets, headers, tubes, and fins, creating high quality "indestructible" radiator.
All Koyo Racing series radiators have "OE Specification" mounting location for stock mounting without major modifications; however we recommend using aftermarket electric fans for the best results. Koyo Hyper Radiator Caps are also available to increase your cooling system pressure to 1.3 bar for increased cooling capacity. Racing series radiators were made for manual transmission only, however with a separate automatic transmission cooler; one can use the Koyo Racing Radiator with automatics for increased cooling capacity.

Folks, I know this is hard to believe, but this cheap radiator is the best option we have for cooling the SR20DET. Yes it has plastic end tanks and is basically the same thickness as the stock radiator. But the copper and brass core is way better at dissipating heat then the fancy shiny expensive aluminum Koyos. I ran this with the stock shroud and fan. It would work just fine with an electric setup. the fan is just for when the car is idle or moving very slowly anyway. I drove the thing every day. I spent hot summer days with the A/C on in traffic and the temp never rose. Going full tilt on track days didn't cause me to over heat either. I ran a stock temp thermostat too since I don't like the crude way of prevent temp spikes with a low temp one. The engine is designed to run at it's operating temp. Running cooler is bad.
