The 5 Best magnetic Block heaters (2023 reviews)

The abn heater pad's material feels more premium than its price would suggest. This item warms the oil pan and oil during cold weather which makes the engine start easier. It doesn’t get any hotter when attached to the pan. The battery warmer car pad heater also reduces wear and tear, increases engine longevity, and extends transmission life. This process will protect the heater and also keep the pad from un sticking.

This is more of a customization rather than a bolt-on part. It installs easy and stays there. It takes 8+ hours to raise the temp any significant amount with this unit or keep it plugged in all the time, which is NOT an acceptable option. It is good as a block heater but does help a lot.
