For Honda ATV and dirt bike riders who want a little more pep and hate buying disposable filters! This K&N HA-0510 is a high-performance, washable and reusable air filter. It's designed to flow more air than a standard paper filter, which can give you a bit more horsepower and better throttle response. The best part? You clean it and use it again and again. It's built tough for off-road and dusty conditions—K&N filters are famous for that. When it gets dirty, you just use their special K&N Filter Cleaner kit (sold separately) to wash it out, re-oil it, and it's good as new. Saves you money in the long run and is better for the planet. Generally, you won't need to re-jet your carburetor just for installing this filter, even at higher altitudes. It comes with a 1-year warranty. A smart upgrade for any Honda off-road machine.
