Cold Weather Performance

Optimized heater design and placement in the intake air stream ensure you get the most efficient heating possible with a single, 700W heating element. For the coldest weather customers who experience sustained temperatures below 23°F (-5°C), our cold weather kit (FPE-CUMM-IAH-X2) adds an additional 700W heating element – together this combination has been tested and validated for startability down to -35° Celsius! Compared with other kits on the market, the Fleece Performance kit achieves the same levels of cold temperature startability with lower wattage and less strain on your grid heater relay!
