Your cart is empty.A frost plug heater is an electric heater that heats the engine of a vehicle to give quicker starts and protects your engine from damage that can occur during cold weather starts. Warmed engines also deliver better fuel economy, plus improves oil flow to provide better lubrication to the engine, which reduces wear and increases engine life. The frost plug heater also cuts back on pollution as it aids in vaporization of fuel, thereby cutting back on emissions.

Bought a pair of these, 1 failed to heat after 6 months, the other one started to leak about the same time. Contacted Kat's go no response after 2 contact attempts. Very poor quality.

This was installed on a CASE front end loader and works like a charm. Other ( smaller ) heaters would need to be powered all the time but this only needs to be plugged in an hour before you want to start it. Great product and will probably get several more.

This heater solved a problem I had with heating my skid steer in the cold winter months. Although it's only rated at 400 watts, this plug heater get very hot quickly (less than 30 minutes), and you must be careful not to touch any of the metal when unplugging it.
