When it comes to cooling components, Koyo's quality and design is unmatched. Their aluminum radiators are designed to keep your engine cool even under some of the harshest conditions. Koyo radiators are made from light weight aluminum and are made for street and track use. They use a fin and tube pitch which significantly increases its surface area while still allowing for excellent air circulation through the radiator. All of their racing radiators are Nocolok brazed and are made as a direct bolt in with no engine modifications necessary. They retain mounts for the stock fan shrouds and fans as well.

Special Notes:

  • Core Size: 14.5" x 26.4"
