Keep your Honda ATV running smooth with this handy tune-up kit! It includes everything you need for basic maintenance: a high-quality foam air filter (replaces OEM #17254-HN1-000), an oil filter (fits HF113/KN113 specs), and a spark plug. The air filter measures about 5\ long with a 5.24\ outside diameter, and the oil filter is 52mm OD x 37mm height. This kit fits a bunch of popular models like the TRX400EX Sportrax (1999-2008), Foreman 500 (2012-2016), and Rancher 420 (2014-2016) in both 4x4 and 2x4 versions. Easy to install yourself if you're handy—just swap out the old parts. Replacing these regularly (every 3 months or so) helps protect your engine from dirt, improves airflow, and ensures peak performance. A cost-effective way to extend your ATV's life and avoid bigger repairs down the road.
