This is a brand new SPAL replacement fan with aluminum mounting brackets for the 2013-2019 Yamaha Raptor 700 ATV. The O.E. number of the fan that this replaces is 1PE-E2405-00-00. The aluminum brackets bolt right on to existing mounts and is an easy install. This fan is 440 cfm which is HIGHER cfm than the stock fan at half the cost. The problem with most ATV's IS NOT the radiator it's the fan being insufficient.
