Since the S&B Particle Separator ejects 94% of the dust before it reaches your stock filter, you won't have to replace your filter as frequently saving you time and money. When installed on the upper roll bar, the Particle Separator provides RAM air to the engine. With this additional airflow, your Polaris General will maintain the highest level of performance in horsepower and fuel economy. The versatile brackets works with virtually any Polaris General roof configuration. Attached to the top rollbar, the brackets ensure a secure fit. The Particle Separator is also designed to work with or without a rear window installed. Install a Particle Separator on your Polaris General and if your stock air filter doesn't last for a year, S&B will give you a replacement filter for FREE.
