K&N INTAKE SYSTEM

In the early 1960s two motorcycle racers Ken Johnson and Norm McDonald (K&N) developed a ground-breaking new idea for an air filter. After experimenting with numerous types of filter media they discovered that an oiled cotton design allowed the filter to not only capture contaminants very efficiently but also allowed it to be washed and reused and the original K&N High-Flow Air Filter was born. Five decades later K&N is still innovating industry-leading filtration technology. In addition to performance air filters K&N® now manufactures a variety of other protection and performance products including air intake systems oil filters & fuel filters with a reputation for exceptional quality and customer service.

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 airflow and longer service intervals than standard RK-series air intake filters. Larger or custom engine builds most often benefit from higher levels of airflow 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 aluminium backing plate mounts directly to the throttle body via an aluminium integrated internal-run breather system. A durable mounting gasket is also included to help absorb vibration. The brilliant shine on this custom flare-shaped chrome cover give this air intake makes an impression on and off the road.
