It's no secret that the Polaris Razor has had issues with its air filtration system. Large enough issues that some Razors have has engine damage due to dust particles getting into the motor. We got so frustrated with the problem here at www.motocurb.com that we developed our own pre air filter that eliminates and cleans the air before entering the air filter and increases horse power. Please watch the video it is a comprehensive installation. If you are interested in learning more about ATV and UTV news visit us here.
