Description

K&N’s Street Metal Series High-Flow Air Intake Systems provide a good looking appearance, offer increased airflow and deliver more horsepower & torque to your Harley-Davidson motorcycle. These intake systems increase power by eliminating the stock OE air cleaner and replacing it with a complete High-Flow Air Intake System. The sturdy, custom aluminum backing plate mounts directly to the throttle body via an aluminum integrated, internal-run breather system. The intake system comes with a K&N Air Filter for high air flow and long service intervals. A durable mounting gasket is also included to help absorb vibration. The K&N High-Flow Air Filter is washable, reusable, pre-oiled and ready for installation. Simple designed custom covers give this air intake good looks while powering down the highway or at your local show. This part fits the following models: HARLEY DAVIDSON FLHP Road King Police 103 CI (2009 - 2012) HARLEY DAVIDSON FLHR Road King 103 CI (2012 - 2016) 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 - 2016) HARLEY DAVIDSON FLHTCU Ultra Classic Electra Glide 103 CI (2013 - 2013) HARLEY DAVIDSON FLHTCU Ultra Classic Electra Glide 96 CI (2008 - 2011) HARLEY DAVIDSON FLHTCUL Electra Glide Ultra Classic Low 103 CI (2015 - 2016) 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 (2011 - 2014) HARLEY DAVIDSON FLHTK Ultra Limited 103 CI (2015 - 2016) HARLEY DAVIDSON FLHTKL Ultra Limited Low 103 CI (2015 - 2016) HARLEY DAVIDSON FLHTP Electra Glide Police 103 CI (2009 - 2012) HARLEY DAVIDSON FLHX Electra Glide Special 103 CI (2016 - 2016) HARLEY DAVIDSON FLHX Street Glide 103 CI (2012 - 2016) HARLEY DAVIDSON FLHX Street Glide 96 CI (2008 - 2011) HARLEY DAVIDSON FLHXS Street Glide Special 103 CI (2014 - 2016) HARLEY DAVIDSON FLHXXX Street Glide Trike 103 CI (2010 - 2011) HARLEY DAVIDSON FLRT Freewheeler 103 CI (2015 - 2016) 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 - 2017) 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 103 CI (2015 - 2016) HARLEY DAVIDSON FLTRX Road Glide Custom 103 CI (2012 - 2014) HARLEY DAVIDSON FLTRX Road Glide Custom 96 CI (2010 - 2011) HARLEY DAVIDSON FLTRXS Road Glide Special 103 CI (2015 - 2016) HARLEY DAVIDSON FXSB Breakout 103 CI (2016 - 2017) This list is a sample of all the compatible motorcycles for this part.
