K&N’s Street Metal Series High-Flow Air Intake Systems provide attractive styling, offer increased airflow and deliver more horsepower & torque to your Harley-Davidson motorcycle. These air intake systems eliminate the stock OE air cleaner and replace it with a complete high-flow air intake system to increase power. The sturdy, custom aluminum backing plate mounts directly to the throttle body via an aluminum integrated, internal-run breather system. The air intake system comes with a K&N Air Filter for high air flow and long service intervals. The K&N air filter is washable, reusable, pre-oiled and ready for installation. To help absorb vibration, a durable mounting gasket is also included. An elegant tear-drop shaped chrome cover make this air intake the perfect complement to any of Harley’s beautiful designs.
