SE-R Koyo radiator....$325, you read that right, $325 these are almost always in stock and can ship the same day!

***Update, If you are running a JGY turbo kit/intercooler kit, then you will probably need one of these. With an ambient temperature of 85F outside, driving at 65mph we typically see engine water temp of 205 to 210 with the factory setup. With our Koyo/fan kit, we see temps lower to about 185. Running the A/C on the factory setup pushed the temp to over 220. Running the A/C with the Koyo kit was about 195F. U12/Gti-r setups work fine with this kit and minimal work is required to install them. U13/Avinier setups........it's a tight fit, but it fits. We suggest putting the intercooler piping in the car first, then installing the radiator last (with the fans already installed on the radiator). Some applications may require shortening the intercooler kit at the turbo section by about 1/2 an inch. See photo below.
