Description

K&N 57i Performance Kit Harley Softail/Dyna 2001-2015 (57-1125) K&N 57i Generation II Induction Kits are built primarily for European vehicles. They come with K&N's Million Mile Limited Warranty™. These intake kits use only non-metallic rotationally molded tubes that can reduce air temperature and decrease intake sound over a metal tube. Restriction can exist BETWEEN an air filter and the engine reducing the benefit of a K&N Air Filter alone. The weakest link in the airflow ''chain'' robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the engine. K&N Air Intake Kits virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into an engine, which translates into POWER. 57i Intakes are not legal for use in California and other US States adopting California emission standards. - Guaranteed to increase horsepower - Designed to improve throttle response and engine sound - Replaces entire factory air intake system - Washable and reusable lifetime air filter - K&N Million Mile Limited Warranty - Lasts up to 100,000 miles before service is required (depending on driving conditions) - Easy to install, usually in 90 minutes or lessThis part fits the following models:HARLEY DAVIDSON FLD Switchback 103 CI (2012 - 2016)HARLEY DAVIDSON FLHR Road King 96 CI (2007 - 2007)HARLEY DAVIDSON FLHRC Road King Classic 96 CI (2007 - 2007)HARLEY DAVIDSON FLHRCI Road King Classic F/I 88 CI (2002 - 2006)HARLEY DAVIDSON FLHRI Road King F/I 88 CI (2003 - 2006)HARLEY DAVIDSON FLHRS Road King Custom 96 CI (2007 - 2007)HARLEY DAVIDSON FLHRSI Road King Custom F/I 88 CI (2004 - 2006)HARLEY DAVIDSON FLHT Electra Glide Standard 96 CI (2007 - 2007)HARLEY DAVIDSON FLHTC Electra Glide Classic 96 CI (2007 - 2007)HARLEY DAVIDSON FLHTCI Electra Glide Classic F/I 88 CI (2002 - 2006)HARLEY DAVIDSON FLHTCU Ultra Classic Electra Glide 96 CI (2007 - 2007)HARLEY DAVIDSON FLHTCUI Electra Glide Ultra Classic F/I 88 CI (2002 - 2006)HARLEY DAVIDSON FLHTI Electra Glide Standard F/I 88 CI (2003 - 2006)HARLEY DAVIDSON FLHX Street Glide 96 CI (2007 - 2007)HARLEY DAVIDSON FLHXI Street Glide F/I 88 CI (2006 - 2006)HARLEY DAVIDSON FLS Softail Slim 103 CI (2012 - 2015)HARLEY DAVIDSON FLSTC Heritage Softail Classic 103 CI (2012 - 2015)HARLEY DAVIDSON FLSTC Heritage Softail Classic 96 CI (2007 - 2011)HARLEY DAVIDSON FLSTCI Heritage Softail Classic F/I 88 CI (2002 - 2006)HARLEY DAVIDSON FLSTF Fat Boy 103 CI (2012 - 2015)HARLEY DAVIDSON FLSTF Fat Boy 96 CI (2007 - 2011)HARLEY DAVIDSON FLSTFB Softail Fat Boy Lo 103 CI (2012 - 2015)HARLEY DAVIDSON FLSTFB Softail Fat Boy Lo 96 CI (2010 - 2011)HARLEY DAVIDSON FLSTFI Fat Boy F/I 88 CI (2001 - 2006)HARLEY DAVIDSON FLSTI Heritage Softail F/I 88 CI (2006 - 2006)HARLEY DAVIDSON FLSTN Softail Deluxe 103 CI (2012 - 2015)HARLEY DAVIDSON FLSTN Softail Deluxe 96 CI (2007 - 2011)HARLEY DAVIDSON FLSTNI Softail Deluxe F/I 88 CI (2005 - 2006)HARLEY DAVIDSON FLSTSB Softail Cross Bones 96 CI (2008 - 2011)HARLEY DAVIDSON FLSTSC Softail Springer Classic 96 CI (2007 - 2007)HARLEY DAVIDSON FLSTSCI Softail Springer Classic F/I 88 CI (2005 - 2006)HARLEY DAVIDSON FLSTSI Heritage Springer F/I 88 CI (2001 - 2003)HARLEY DAVIDSON FLTR Road Glide 96 CI (2007 - 2007)HARLEY DAVIDSON FLTRI Road Glide F/I 88 CI (2002 - 2006)HARLEY DAVIDSON FXCW Rocker 96 CI (2008 - 2009)HARLEY DAVIDSON FXCWC Rocker C 96 CI (2008 - 2011)HARLEY DAVIDSON FXD Dyna Super Glide 96 CI (2007 - 2010)HARLEY DAVIDSON FXDB Street Bob 103 CI (2014 - 2017)HARLEY DAVIDSON FXDB Street Bob 96 CI (2007 - 2013)HARLEY DAVIDSON FXDBI Street Bob F/I 88 CI (2006 - 2006)HARLEY DAVIDSON FXDC Super Glide Custom 103 CI (2014 - 2014)HARLEY DAVIDSON FXDC Super Glide Custom 96 CI (2007 - 2013)HARLEY DAVIDSON FXDCI Dyna Super Glide Custom F/I 88 CI (2005 - 2006)HARLEY DAVIDSON FXDF Fat Bob 103 CI (2012 - 2017)HARLEY DAVIDSON FXDF Fat Bob 96 CI (2008 - 2011)HARLEY
