Kat's 11420 400 Watt 36.5mm Frost Plug Heater

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.
