UNI Air Filter for the Polaris RZR 170 is a high flow foam filter. The air filter is created with "Open Cell" Polyurethane Foam that is developed to be used with foam filter oil. It is designed to suspend the oil in the filter almost like a web which makes it almost impossible for dirt particles to pass through. The outer layer is a course thick layer that will grab all the larger particles of dirt. The finer soft inner foam layer traps extremely tiny dirt particles. They call this their Original Two-Stage Foam Filter design. Not only were these filters designed for dusty environments, but they are also made to increase performance. These filters have much more flow and will help produce more horsepower and more torque than your average filters. Giving you a much crisper and smooth ride! These air filters do not come pre-oiled and must be oiled once purchased.
