Autolite engineers have developed plugs in many heat ranges to suit all engine applications. They range from COLD through MEDIUM; and HOT to EXTREMELY HOT. Rules for selecting the correct plug are to follow manufacturer’s specifications. COLD MEDIUM HOT
May 11, 2018 · Let’s first define what is a hot versus a cold plug. Looking at a spark plug center ceramic insulator, if the area between the ceramic and the spark plug outer steel shell is deep, that is a hotter heat range plug. Conversely, if the ceramic contacts the shell very close to the open end of the shell, this would be a much colder spark plug.
In order to gather this information you must know the thread diameter, length and seat type required by your cylinder head. Do not use a removed spark plug as a guide for determining proper shell dimensions. Failure to get accurate information can result in decreased performance and damaged engines.

You can find out how many spark plugs your car has, where they are located, and how to remove them by consulting the service manual. Spark plugs are typically removed with a ratcheting socket, drive wrench, and an extension bar. To be safe, let the engine cool completely if you ran it before checking the spark plugs. It’s possible that your spark p...
Heat range is a measure of how much heat the insulator can take to maintain proper plug temperatures and prevent it from overheating to the point where pre-ignition occurs; these days, you’re definitely hearing about heat range when people are talking about bolt-on boost projects. The compression ratio or cylinder pressure of an engine is what dete...
After 30,000 to 50,000 miles, depending on the vehicle, you should change the spark plugs if they are made of copper or nickel. Spark plugs made of platinum or iridiumare more durable than the more common copper or nickel varieties. If not specified otherwise, they should be replaced every 60,000 miles to 150,000 miles.
Early detection of failure indicatorsis essential for avoiding catastrophic breakdowns caused by seemingly minor issues. Plugs, as we’ve said before, serve as eyewitnesses within the combustion chamber, providing information before the levee breaks. The presence of oil on the plug indicates a serious problem. The presence of ash, specifically oil a...
A spark plug’s heat range is the degree to which it disperses heat. Spark plugs with high heat dispersal are referred to as cold, while plugs with less heat-dissipating characteristics are known as hot. The structure of the spark plug affects the heat rating: Length of insulator nose; Surface area; Material of center electrode; Position of ...
