K&N RK SERIES HI-FLOW AIR FILTER

K&N claims you get more horsepower from your Twin Cam engine when this extra large "RK series" filter is fitted. Built around the legendary K&N High-Flow Air Filter, the new RK Series assembly includes a billet aluminum cover and back plate that eliminates external breathers and features a built-in, dyno-tuned velocity stack. The result is a significant airflow increase to the engine without sacrificing filtration. This RK Series assembly boasts superior filtration.
Note: European Softail 2007-2015, European Dyna 2007-2016 & European Touring 2007 are equipped with an Active Intake Sensor that must be removed when installing an aftermarket air cleaner. When you install a ZPN 702022 "Trick-Box", which is a plug-in module for the stock wiring harness, you avoid a warning light coming on at your dash.
