Description
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. At the heart of this system is K&N's Air Filter which offers increased air flow, long service intervals, and is pre-oiled ready to be installed. The chrome custom cover plate gives this air intake good looks while powering down the highway or at your local show.
