K&Ns RK Series Street Metal high flow air intake systems 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 and has a built in breather system to direct pressure from the breather bolts into the throttle body opening and not out into the air filter. Street Metal air intake systems include a high flow air filter which provids low restriction airflow and long air filter service intervals. K&N Street Metal series high flow air intake systems are equipped with custom designed aluminum covers to make sure your air cleaner looks good while powering down the highway or at your local show.
