New K&N Air Filter #KN631119

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.

The K&N 63-1119 AirCharger air intake system replaces the restrictive factory air filter and air intake housing in some Yamaha YXR660 Rhino models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten airflow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 63-1119 air intake comes with a K&N XStream Top air filter designed for higher airflow and durability. Air is directed through a black powder-coated aluminium intake tube and into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory side vent hose as well as a supplied small air filter for the crankcase vent hose. The oversized, inverted cone-shaped air filter comes with a water repellent DryCharger filter wrap to protect the filter from moisture. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points.
