The Kat's 11424 is a 400-watt frost plug heater designed to keep your engine warm in cold weather conditions. This electric engine block heater replaces a 35mm frost plug (freeze plug) and heats the engine coolant from within, providing reliable cold weather starting protection.

Key Features:

• 400-watt heating element for efficient engine warming

• Improves fuel economy and reduces emissions in cold weather
• Protects engine from cold-start damage

How It Works:

This frost plug heater installs in place of an existing engine frost plug and uses electric heat to warm the engine coolant. By pre-heating your engine, you'll experience quicker starts, better fuel vaporization, improved oil circulation, and reduced engine wear. The heater helps your vehicle reach operating temperature faster while cutting down on harmful cold-start emissions.

Installation:

The heater replaces a 35mm frost plug in your engine block. Professional installation is recommended to ensure proper fit and seal. Once installed, simply plug the heater into a standard 120V outlet 2-3 hours before starting your vehicle in cold weather.
