S&B Filters, Fontana, Calif., with over 40 years experience in the automotive industry, makes its official debut in the off-road industry with the S&B Particle Separator for the Polaris 2012-16 RZR 900 and 2014-15 RZR 1000. This unique mod applies the same air filtration technology used by military helicopters in dusty, desert terrain and works by removing 94% of dust from the airflow, so your filter will last over 15x longer. With your filter engulfing cleaner air, your UTV will perform stronger when other's filters start to clog. Go further, faster and save money. Testing conducted in a climate controlled lab according to the ISO 5011 Test Procedure on a 2015 Polaris RZR 1000. Results may vary.
