16-Oz Design Engineering Heater Hotter

FASTER CABIN HEAT IN EXTREME COLD: Heater Hotter is design engineered to accelerate heat transfer from the engine to the antifreeze, delivering warm air up to 50% faster in sub-zero winter temperatures.
DEFROST WINDOWS IN HALF THE TIME: Warm air reaches your defroster faster, helping melt ice, frost, and snow quickly while reducing scraping and windshield wait time.
ENHANCES REMOTE START PERFORMANCE: Designed to improve heat efficiency during warm-up, Heater Hotter maximizes the effectiveness of remote starters for faster cabin comfort.
IMPROVES WINTER HVAC EFFICIENCY: Design engineered for harsh winter climates, Heater Hotter allows your vehicle’s HVAC system to operate more efficiently in cold conditions.
SAFE, LONG-LASTING, AND EASY TO USE: Compatible with all antifreeze types and aluminum radiators; pour directly into the radiator and allow it to cycle and mix with existing antifreeze—performance does not dissipate over time.
