KN Street Metal Intake System

Air Cleaner Assembly

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.
