Product Details

The KatsHeaters 11421 is a 400-watt frost plug (freeze plug) engine block heater designed to replace a 35mm frost plug in your engine block. This direct-replacement heater warms the engine coolant and block, ensuring easier cold-weather starts, reduced engine wear, and improved cabin heating performance in freezing temperatures.

Key Features:

  • 400-watt heating element provides efficient engine warming
  • Fits standard 35mm (1-3/8 inch) frost plug openings
  • Direct replacement for existing freeze plug
  • Includes installation gasket for proper sealing
  • 120-volt AC operation with standard plug
  • Reduces cold-start engine wear and improves oil circulation
  • Faster cabin heat and defrost performance

Frost plug heaters are among the most efficient engine heating solutions, transferring heat directly into the coolant system. Simply plug in the heater 2-4 hours before starting your vehicle in cold weather for optimal results. Professional installation recommended as it requires draining coolant and removing an existing frost plug.

Easy online ordering

fast shipment and was exactly what i had ordered

Awesome price, fast shipping, and accurate tracking. I ordered from Autoplicity because of the great reviews and they didn't disappoint. There is no question that I will be ordering again.

So far so good

Had instock, good price

You need to display more info on clamp dimensions - having to visit other sites to get data necessary to fit to vehicle

Best price. Easy to order.

Great prices and prompt shipping

I saw nothing but good reviews and the money back guarantee, these together helped me finalize my decision to order from this site. I ordered just before the weekend started so I think it took my order a little longer to process. I was relieved to find that my order was shipped on the day I ordered it, It just took a little while for the email traffic to catch up. So far things have been good!!!
