dealer can perform any service that may be necessary for your vehicle.
POLARIS also recommends POLARIS parts, however equivalent parts may be

supplied by an aftermarket parts manufacturer reduces the effectiveness of the
vehicle's emission controls. Tampering with emission controls is prohibited by
federal law.
