The K&N Engineering 57-1134 Performance Air Intake System is designed for select Harley-Davidson Touring models. It replaces the restrictive stock OE air cleaner with a complete K&N performance intake system featuring a high-flow air filter and cast aluminum intake tube.
The system includes a die-cast aluminum throttle-body mounting plate and mounting hardware. By increasing airflow to the engine, the intake system is designed to help increase power while giving the motorcycle an aggressive appearance.
The included high-flow air filter is washable and reusable, with cleaning intervals of up to 100,000 miles under normal highway driving conditions. The system carries K&N's Million Mile Limited Warranty and is CARB exempt and street legal in all 50 states. California Executive Order number D-269-59 applies.
This intake system fits select 2008–2009 Harley-Davidson Touring motorcycles, including Road King, Road King Classic, Screamin Eagle Road King, Electra Glide Standard, Electra Glide Classic and Road Glide models. Verify the listed vehicle application before ordering.
