A 10 row radiator is suitable for road use, a 13 row for fast road/sport, a 16 row for sport/sprints, and a 19 row for competition/race.
Oil Cooler Installation Kits are available separately, allowing you the choice of cooling depending upon your application, and include ready assembled hoses. Made in the UK.
