Description

The K&N RK-3930 Air Intake System was designed to get more horsepower from your Twin Cam Harley-Davidson engine. Built around the legendary K&N High-Flow Air Filter, this RK Series assembly includes an innovative powder coated billet aluminum 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 retains a factory appearance by utilizing the stock air cleaner cover.This part fits the following models:HARLEY DAVIDSON FLHP Road King Police 103 CI (2009 - 2012)HARLEY DAVIDSON FLHR Road King 103 CI (2012 - 2013)HARLEY DAVIDSON FLHR Road King 96 CI (2008 - 2011)HARLEY DAVIDSON FLHRC Road King Classic 103 CI (2011 - 2013)HARLEY DAVIDSON FLHRC Road King Classic 96 CI (2008 - 2010)HARLEY DAVIDSON FLHRSE4 Screamin Eagle Road King 110 CI (2008 - 2008)HARLEY DAVIDSON FLHT Electra Glide Standard 96 CI (2008 - 2010)HARLEY DAVIDSON FLHTC Electra Glide Classic 103 CI (2012 - 2013)HARLEY DAVIDSON FLHTC Electra Glide Classic 96 CI (2008 - 2011)HARLEY DAVIDSON FLHTCU Electra Glide Ultra Classic 103 CI (2012 - 2012)HARLEY DAVIDSON FLHTCU Ultra Classic Electra Glide 103 CI (2013 - 2013)HARLEY DAVIDSON FLHTCU Ultra Classic Electra Glide 96 CI (2008 - 2011)HARLEY DAVIDSON FLHTCUSE5 CVO Ultra Classic Electra Glide 110 CI (2010 - 2010)HARLEY DAVIDSON FLHTCUTG Tri Glide Ultra Classic 103 CI (2009 - 2013)HARLEY DAVIDSON FLHTK Electra Glide Ultra Limited 103 CI (2010 - 2013)HARLEY DAVIDSON FLHTP Electra Glide Police 103 CI (2009 - 2012)HARLEY DAVIDSON FLHX Street Glide 103 CI (2012 - 2013)HARLEY DAVIDSON FLHX Street Glide 96 CI (2008 - 2011)HARLEY DAVIDSON FLHXXX Street Glide Trike 103 CI (2010 - 2011)HARLEY DAVIDSON FLS Softail Slim 103 CI (2016 - 2017)HARLEY DAVIDSON FLSS Softail Slim S 110 CI (2016 - 2017)HARLEY DAVIDSON FLSTC Heritage Softail Classic 103 CI (2016 - 2017)HARLEY DAVIDSON FLSTF Fat Boy 103 CI (2016 - 2017)HARLEY DAVIDSON FLSTFB Softail Fat Boy Lo 103 CI (2016 - 2016)HARLEY DAVIDSON FLSTFBS Fat Boy S 110 CI (2016 - 2017)HARLEY DAVIDSON FLSTN Softail Deluxe 103 CI (2016 - 2017)HARLEY DAVIDSON FLTR Road Glide 96 CI (2008 - 2010)HARLEY DAVIDSON FLTRU Road Glide Ultra 103 CI (2011 - 2013)HARLEY DAVIDSON FLTRX Road Glide Custom 103 CI (2012 - 2013)HARLEY DAVIDSON FLTRX Road Glide Custom 96 CI (2010 - 2011)HARLEY DAVIDSON FXSB Breakout 103 CI (2016 - 2017)This list is a sample of all the compatible motorcycles for this part.
