Product Details

The Kat's 11423 is a 400-watt frost plug engine block heater designed to warm your engine before starting in cold weather conditions. This direct-immersion heater installs in place of a 1/2" NPT frost plug (also called expansion plug or freeze plug) and heats the engine coolant from within the engine block.

Key Features:

  • 400-watt heating element provides efficient engine warming
    • li>1/2" NPT thread size fits standard frost plug openings
  • Direct coolant immersion for fast, even heat distribution
  • Reduces engine wear during cold starts by maintaining oil viscosity
  • Improves fuel economy and reduces emissions in cold weather
  • Standard 120V AC power cord for easy connection

Installing a frost plug heater keeps your engine block warm during freezing temperatures, ensuring reliable cold-weather starts while extending engine life. Pre-warming the coolant allows oil to flow freely from the first moment of startup, dramatically reducing metal-on-metal wear. Additionally, a warmed engine reaches operating temperature faster, improving fuel vaporization and reducing harmful cold-start emissions.

Great website

Did an extensive search on line to find the best price available, and autoplicity was definitely the best. Now I no longer need to spend more time searching, I will go straight to autoplicity!

Easy to order and find parts

you say you have the item in stock

I searched around and Autoplicity had the best deal by over $40. Was it to good to be true? Definitely not. I just had to verify I had the right part number. Easy to pay with Google checkout, and the order shipped very quickly. Received email updates on order receipt, shipping, and delivery. Shipping was cheap too. I would definitely buy from them again.

Great website, this makes car part buying real easy!

Fast and accurate

They have the best unbelievable prices and availability on all kinds of automotive products on the market and like I said the prices are great i will buy from here in the future

They had the best price I could find, anywhere, for Royal Purple HPS oil (and I spent hours searching). I ordered a case on Sunday night and it arrived on Wednesday (standard shipping) from half-way across the country. For standard shipping, that's pretty fast. They must have send it out early Monday morning, at the latest.<br><br>I'm very satisfied with my experience, and I'll definitely be ordering from them again, when I need another case of oil.

Excellent prices and quick shipping. Will definitely use again.

Had a little trouble adjusting the number of parts to order. Once on Amazon payment it wasn't intuitive on how to correct the quantity. I called tech services and they got me there quickly. Thanks.

Great Prices and fast, fast shipping. I will definitely do business with them again.
