Street Metal Intake System - Hammer

• Product Details

  K&N's Street Metal Series High-Flow Air Intake Systems provide a good looking appearance, offer increased airflow and deliver more horsepower and torque to your Harley-Davidson motorcycle. These intake systems increase power by eliminating the stock O.E. 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.
