Kuryakyn chrome butterflies for pro-series & pro-r hyperchargers

PRO-R & PRO-SERIES HYPERCHARGER REPLACEMENT COMPONENTS Capable of supporting engine builds that produce up to 140+ HP Since its inception, the Hypercharger has continued to evolve to meet the needs of the performance minded rider. What you see here is without a doubt the best flowing Hypercharger we have ever produced. The interior shapes, especially the critical radius leading into the carb or throttle body, have been carefully designed. The outer cover incorporates an additional scoop to direct air into a high-flow, washable foam filter element that seats snuggly in the end of a round K&N filter element. This filter assembly is one of the best flowing on the market & is capable of supplying enough air to even the highest output street motors. The frontal opening is huge & as with all Hyperchargers, the vacuum operated butterflies allow almost unrestricted airflow to the filter under high-load riding situations. Pro-R Hyperchargers come complete with mounting hardware & crankcase breather kits.
