The Sparks Racing Intake Restrictor for the Polaris RS1 and RZR 1000 XP is designed to limit the power output of the car to help make the transition to the RS1 or RZR 1000 XP more comfortable for young or inexperienced drivers. This is also the only Best In The Desert approved intake restrictor. The restricted class is the perfect solution to a racer who wants to build a car one time and can advance into other classes without building a new racecar every year. Tuning is not required to run this restrictor. For racers trying to race at the top of the restricted class, we recommend the Sparks Racing exhaust and tuning which will improve drivability and performance.
