733828 Fits 2004 to Present XL Sportster Replacement Filter Element

This K&N RK Series conversion kit replaces the restrictive stock intake components with a high-flow filtration system designed for Harley-Davidson motorcycles. The assembly features a powder-coated billet aluminum back plate with a built-in, dyno-tuned velocity stack to optimize airflow. By integrating internal breathers, it eliminates the need for external hoses, maintaining a clean aesthetic while allowing the use of the original factory air cleaner cover. A laser-etched beauty ring adds a finished look to the filter element. K&N’s signature pleated cotton media provides superior airflow and protection, making this a staple upgrade for riders seeking improved engine efficiency and a more responsive throttle.
