This new XDR Performance Air Filter is cleanable, reusable and comes pre-oiled. The eight layer cotton gauze design captures more dust and dirt particles than typical 4 and 6 layer filters to maximize the performance of your side by side. Features include 0.50-inch deep pleats and an overall wide surface area for optimum airflow. This filter can last a lifetime since it is washable and can be re-oiled during regular maintenance intervals. This replaces the factory paper filter, fitting in the factory airbox. Be sure to pick up a new Air Filter Refresh kit, part #615001, to keep your filter system fresh and breathing strong, and for severe duty use Pre-Filter Wrap #615005 for an extra layer of protection.
