CSF joined forces with GT-R tuning specialist, Cicio Performance from Atlanta, GA to develop and bring to market the industry's best drop-in fit Nissan R35 GT-R oil cooler. At CSF we don't take the word "best" lightly, and neither does Cicio Performance with its record-breaking cars. Tested in TSM's very own 1700HP GT-R. The new TSM R35 GT-R oil cooler is a perfect high-performance solution for all aspects of motorsports, including circuit racing, drag racing, and endurance racing to name a few. Not only are you getting a performance upgrade, but since it's drop-in-fit, it also has immense value when needing a replacement for the OEM cooler in the case of a failure.
