The Same Technology Military Helicopters Use To Maintain Power In Extremely Dusty Conditions Is Now Available For Your Off-road UTV. S&B's Particle Separator Removes 94% Of Dust From The Airflow Before It Even Reaches The Stock Filter Allowing Your Filter To Last Over 15 Times Longer Before Reaching Capacity. This Dramatically Extends The Lifespan Of Your UTV's Air Filter Maintaining Horsepower And Torque For A Much Longer Period Of Time. With The S&B Particle Separator, One (1) Air Filter Will Last As Long As 15 Would Without The S&B System. The S&B Particle Separator Pays For Itself And Even Saves You Money Because You Will Buy Fewer Filters.
