KatsHeaters 11412 400 Watt 30mm Frost Plug Engine Block Heater

The Kat's 11412 is a 400-watt frost plug engine block heater designed to warm your engine before starting in cold weather conditions. This direct-heating element installs in place of a 30mm frost plug (also called a freeze plug or expansion plug) and warms the coolant and engine block from the inside.

Key Features:

• 400-watt heating element provides efficient engine warming
• Fits standard 30mm (1-3/16") frost plug openings
• Reduces engine wear during cold starts by ensuring proper oil flow and lubrication
• Improves fuel economy and reduces emissions by promoting better fuel vaporization
• Enables quicker, more reliable starts in freezing temperatures
• Extends engine life by minimizing strain on cold engine components
• 120-volt AC operation with standard grounded plug

Installation requires removal of an existing frost plug and replacement with this heating element. The heater plugs into a standard 120V outlet and should be used with a timer or temperature-controlled outlet for optimal efficiency. Ideal for cars, trucks, tractors, and other gasoline or diesel engines with 30mm frost plug access.
