Easy installation. Works great even on the coldest days.

These heaters are easy to install and work great. However, you drain your battery if you leave it on and the car won't start (oops). I would recommend taking built in fuses with you or using them in a dedicated protected circuit just because there is no real built in protection. EASY installation, has saved my diesel truck from gelling several times.

Pros
  • Use only with metal filters
Cons
  • Weight

Heats up quickly for heating

Heats up quickly and reliably. Other manufacturers had a built-in temperature switch that turned off the heater prematurely. This just kept working. 20 minutes. The only issue worth mentioning is that the velcro doesn't hold the heater as tight as it once slipped off. Maybe my filter is a bit small for this heater. I added a separate elastic velcro to solve this problem. .

Pros
  • 4 in. (10 cm) x 12 in. (30.5 cm); Heater length 9 inches (23 cm)
Cons
  • Minor issues

Working and well made, still needs fuel treatment.

Used for a few weeks at 0°-15°F. Although not warm enough to keep my truck from getting fatter while driving, if I turn off the engine and warm the filter for 20 minutes as per the description, the filter cleans and the truck runs great afterwards . I still have to handle some fuel, which I was hoping to avoid, but I never run into a dilemma. Well built and a perfect match for my 2017 Ram 5500 water separator filter on a 6.7 liter Cummins diesel.

Pros
  • Volts: 12 | Tue: 100 | Amplifier: 8.3 | Plug Type: Blunt End
Cons
  • Cord is shorter than other picks
