The General is a great all-season machine once you close in the cab and add heat. The Firestorm HT_CU_405 pulls heat from the General's engine coolant for up to 18,000 BTU, with adjustable temperature and fan speed. Two defrost vents keep the windshield clear, and separate vents warm the driver and passenger.
What It Does for a General
- Fits 2016-2026 Polaris General per Moto Alliance.
- Two defrost vents aimed at the windshield, plus driver and passenger vents.
- 360-degree vents let you point the heat where you want it.
- Built-in shutoff valve for summer riding.
- Hidden heater core for an OEM look.
Getting the Most Heat
- Let the engine warm up before turning the fan on high.
