Overview of K & N RK Series Street Metal High-Flow Air Intake - RK-3949B

K&N RK-3933X Intake System-Harley Davidson, Custom Assemblies

  • Designed for Harley-Davidson motorcycles
  • Increase horsepower and torque
  • Extra tall air filter design provides even more air flow and longer service intervals than standard RK-series air intakes
  • Easy to install
  • Made in the U.S.A.
  • Backed by K&N Million Mile Limited Warranty
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 which is replaced by a complete high-flow K&N air intake system. This air intake system is constructed with an extra tall K&N air filter providing more air flow and longer service intervals than standard RK-series air intake filters. The extra tall air filter design is intended to be used on larger or custom engine builds that would benefit from higher levels of air flow. Installation is simple with a sturdy, custom aluminum backing plate that mounts directly to the throttle body via an aluminum integrated, internal-run breather system. 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.
