I highly recommend this item to help keep the off-road riding micro particals from possibly entering the engine. Installed on an arctic cat 400 4x4, it also helps extend cleaning periods to the filter!

Installing this filter dramatically improved the throttle response over the factory air filter. Installed on a 2006 arctic cat 400 4x4. I also purchased the dry filter cover to help keep out the small micro stuff for off-road use, which was highly recommended by a friend that is a atv mechanic!

Installed the K&N Cone filter on my Arctic Cat Prowler UTV. I used this as a pre-filter. The factory filter is an oil treated foam filter inside an air box. After one day of riding dirt trails, the factory filter needed to be cleaned. Using the K&N filter as a pre-filter has resulted in not cleaning the factory filter after every ride, but rather cleaning about once every 10-15 rides. I just blow out the K&N filter, and reinstall. I leave the filter dry. The filter does an excellent job! I've used other K&N filters in the past, and have always has great results! Thanks for a great product!
