Built with a robust 48mm core, it is engineered for the serious performance tuner. Increased capacity means better cooling reserve when you need it. Intended for both circuit and daily use, you may double your coolant capacity and see up to 35% increased performance over your stock radiator. Unless noted otherwise, all Koyorad All Aluminum Radiators are Nocolok brazed, designed as a factory fit, direct bolt in with no engine modifications necessary, and retain mounts for the stock fan shrouds and fans.

Note:
