Description
If you’re running a carbureted Yamaha and want measurable gains in throttle response and mid-range power, a high-flow air filter is one of the most cost-effective upgrades available. The K&N RU-2780 eliminates the restrictive stock airbox, allowing your engine to breathe freely and pull more air on demand. This clamp-on design delivers direct intake flow to the carburetor—no adapters, no compromises.
Installation requires removing your stock airbox assembly and filter element, but the payoff is immediate: improved acceleration, better fuel atomization at cruise, and a noticeable engine note that reflects the increased airflow. K&N’s washable, reusable media design also eliminates the need for frequent filter replacements, saving you money over time.
