N-Flo Technology
Koyo offer their innovative N-Flo technology, fitting their radiators with "N" shaped internal partitions. This exclusive design allows the coolant to flow through the radiator for longer, and ensures effective cooling across the whole surface (unlike standard radiators, where the coolant usually flows diagonally). N-Flo technology, combined with the high thermal conductivity of the aluminium, guarantees up to 50% better cooling efficiency than stock, lower operating temperatures and improved engine reliability.
