Koyorad: Alloy Radiator (36mm Core): BMW M3/ M4 3.0L I6 Turbo A/T (15-18)
Ideal for use both on and off the track, this Koyo Performance aluminium radiator will considerably improve your engine cooling. Made from aviation grade aluminium, TIG welded and with a high quality, polished finish, it goes directly in place of your existing radiator without any modification : using the same mounting brackets, stock fans and/or shrouds, sensors, drain plugs, etc.
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.
