Kat's 1155 200 Watt Magnetic Heater;

A magnetic heater is an electric heater that heats the engine or transmission 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. Oil and transmission fluids thicken and do not circulate well at cold temperatures. Magnetic heaters transmit heat continuously to keep oils fluid, giving you instant lubrication when starting your engine. Magnetic heaters appeal to the automotive, heavy duty, and farm supply segments, as they have a myriad of uses.
