As some of you know we have been using a Koyo aluminum radiator for the past couple months. We’ve now put 6,000 miles on the car, ran a couple atuoX events and now run a track day with this radiator. We absolutely love it! The car performed awesome over this past weekend at Auto Club Speedway in Fontana, CA. Temperatures were over 105 and the temp didn’t go up at all. We did 4 sessions at 20 minutes at a time. A lot of you have asked how was the install on it and can it be done at home. It absolutely can be done at home with regular tools. We put together a install guide in case you needed some help installing the Koyo Radiator. Visit http://www.koyorad.com/ for more info.
