K&N RK-3947XB Intake System-Harley Davidson

K&N's Street Metal Series High-Flow Air Intake Systems provide attractive styling, offer increased airflow and deliver more horsepower & torque to your Harley-Davidson motorcycle. This series completely eliminates the stock OE air cleaner and replaces it with a high-flow K&N air intake system, increasing power. This intake system uses an extra tall K&N air filter, which means even more air flow and longer service intervals than standard RK-series air intake filters. Larger or custom engine builds most often benefit from higher levels of air flow, so the extra tall filter designs are a perfect choice for more powerful bikes. The K&N high-flow air filter is washable, reusable, pre-oiled and ready for installation, making an already easy install even faster. Just how fast? Less than 90 minutes, in most cases. The sturdy, custom aluminum backing plate 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 black finish on this custom flare-shaped cover give this air intake makes an impression on and off the road.
