The 2019-2023 RZR XP 1000 got updated bodywork and a new dash, so it needs its own heater kit. The Firestorm HT_CU_406-XP1000 is built for that generation, with brackets and hoses sized to the car. It pulls up to 18,000 BTU from engine coolant and splits it between two defrost vents and a vent for each seat.
