The exclusive triple layer foam filter is available in dry or pre-oiled and designed for the most extreme conditions, providing more protection against silt, water, and sand than other air filters. The triple-stage foam eliminates the need for dust and outerwear covers that steal power from your application while lasting longer and allowing for more time to pass between servicing. This triple-layer air filter can be cleaned, reoiled, and reused just like a two-stage filter and is used by factory off-road teams internationally; so don't miss out on this revolutionary air filter.
