K&N Engineering 57-1125 Performance Intake Kit for Select Harley-Davidson Softail and Touring Models
Description

The K&N Engineering 57-1125 Performance Intake Kit replaces the restrictive stock air cleaner on select Harley-Davidson motorcycles with a high-flow air filter and mandrel-bent aluminum intake tube. This design allows more air to flow directly to the engine and is intended to increase power while giving the motorcycle an aggressive appearance.

The kit features a sleek black aluminum intake tube, a billet aluminum throttle-body mounting plate, and mounting hardware. Installation usually takes 90 minutes or less, helping provide a straightforward upgrade for compatible Harley-Davidson applications.

The included high-flow air filter is washable and reusable and can go up to 100,000 miles before cleaning under normal highway driving conditions. This intake system is listed as EPA compliant and includes California Air Resources Board Executive Order number D-269-55.

Fitment includes select 2001 Harley-Davidson Softail models, including the FLSTFI Fat Boy, FLSTSI Heritage Springer, FXSTBI Night Train, FXSTDI Softail Deuce, FXSTI Softail Standard, and FXSTSI Springer Softail, along with select 2002 models including the FLHRCI Road King Classic, FLHTCI Electra Glide Classic, FLHTCUI Electra Glide Ultra Classic, and FLSTCI Heritage Softail Classic.
