K&N’s RK Series was developed to get more horsepower from your Twin Cam® Harley-Davidson® engine. Built around the legendary K&N High-Flow Air Filter, the this RK Series assembly includes an innovative powder coated billet aluminum backplate 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 retains a factory appearance by utilizing the stock air cleaner cover. The RK-3910-1 comes with a larger air filter and longer spacers than the RK-3909-1.Designed to increase horsepower & torqueDyno-tuned velocity stackWashable and reusableExcellent air filtrationProduct SpecificationsEstimated Horsepower Gain 10.76 HP @ 5206 RPMAir Filter Color RedAir Filter Height 2.188 in (56 mm)Air Filter Material Cotton GauzeAir Filter Outlet Shape RoundAir Filter Shape OvalCARB EO Number D-269-35Clamp Material No Clamps RequiredClamp Style No Clamps RequiredClamps Included No Clamps IncludedColor RedFilter Material Cotton GauzeInlet Diameter 2.25 in (57 mm)Mounting Hardware Included YesNeck Flange 2.25 in (57 mm)Overall Height 2.188 in (56 mm)Replacement Filter E-3980Size 9 InchStyle OvalTop Material/Finish Black Powder CoatedTop Style MetalApplication2012 HARLEY DAVIDSON FLSTN SOFTAIL DELUXE 103 CI – w/2-1/4 inch Tall Filter2012 HARLEY DAVIDSON FLSTFB SOFTAIL FAT BOY LO 103 CI – w/2-1/4 inch Tall Filter2012 HARLEY DAVIDSON FLSTF FAT BOY 103 CI – w/2-1/4 inch Tall Filter2012 HARLEY DAVIDSON FLSTC HERITAGE SOFTAIL CLASSIC 103 CI – w/2-1/4 inch Tall Filter2011 HARLEY DAVIDSON FXCWC ROCKER C 96 CI – w/2-1/4 inch Tall Filter2011 HARLEY DAVIDSON FLTRX ROAD GLIDE CUSTOM 96 CI – w/2-1/4 inch Tall Filter2011 HARLEY DAVIDSON FLSTN SOFTAIL DELUXE 96 CI – w/2-1/4 inch Tall Filter2011 HARLEY DAVIDSON FLSTFB SOFTAIL FAT BOY LO 96 CI – w/2-1/4 inch Tall Filter2011 HARLEY DAVIDSON FLSTF FAT BOY 96 CI – w/2-1/4 inch Tall Filter2011 HARLEY DAVIDSON FLSTC HERITAGE SOFTAIL CLASSIC 96 CI – w/2-1/4 inch Tall Filter2010 HARLEY DAVIDSON FXSTC SOFTAIL CUSTOM 96 CI – w/2-1/4 inch Tall Filter2010 HARLEY DAVIDSON FXSTB NIGHT TRAIN 96 CI – w/2-1/4 inch Tall Filter2010 HARLEY DAVIDSON FXCWC ROCKER C 96 CI – w/2-1/4 inch Tall Filter2010 HARLEY DAVIDSON FLTRX ROAD GLIDE CUSTOM 96 CI – w/2-1/4 inch Tall Filter2010 HARLEY DAVIDSON FLSTN SOFTAIL DELUXE 96 CI – w/2-1/4 inch Tall Filter2010 HARLEY DAVIDSON FLSTFB SOFTAIL FAT BOY LO 96 CI – w/2-1/4 inch Tall Filter2010 HARLEY DAVIDSON FLSTF FAT BOY 96 CI – w/2-1/4 inch Tall Filter2010 HARLEY DAVIDSON FLSTC HERITAGE SOFTAIL CLASSIC 96 CI – w/2-1/4 inch Tall Filter2009 HARLEY DAVIDSON FXSTC SOFTAIL CUSTOM 96 CI – w/2-1/4 inch Tall Filter2009 HARLEY DAVIDSON FXSTB NIGHT TRAIN 96 CI – w/2-1/4 inch Tall Filter2009 HARLEY DAVIDSON FXCWC ROCKER C 96 CI – w/2-1/4 inch Tall Filter2009 HARLEY DAVIDSON FXCW ROCKER 96 CI – w/2-1/4 inch Tall Filter2009 HARLEY DAVIDSON FLSTN SOFTAIL DELUXE 96 CI – w/2-1/4 inch Tall Filter2009 HARLEY DAVIDSON FLSTF FAT BOY 96 CI – w/2-1/4 inch Tall Filter2009 HARLEY DAVIDSON FLSTC HERITAGE SOFTAIL CLASSIC 96 CI – w/2-1/4 inch Tall Filter2008 HARLEY DAVIDSON FXSTC SOFTAIL CUSTOM 96 CI – w/2-1/4 inch Tall Filter2008 HARLEY DAVIDSON FXSTB NIGHT TRAIN 96 CI – w/2-1/4 inch Tall Filter2008 HARLEY DAVIDSON FXCWC ROCKER C 96 CI – w/2-1/4 inch Tall Filter2008 HARLEY DAVIDSON FXCW ROCKER 96 CI – w/2-1/4 inch Tall Filter2008 HARLEY DAVIDSON FLSTN SOFTAIL DELUXE 96 CI – w/2-1/4 inch Tall Filter2008 HARLEY DAVIDSON FLSTF FAT BOY 96 CI – w/2-1/4 inch Tall Filter2008 HARL
