Spark plugs come in various heat ranges, commonly referred to as “hot” or “cold” plugs. The heat range of a spark plug refers to its ability to dissipate heat from the combustion chamber. Here’s an explanation of the difference between hot and cold spark plugs: 1. Heat Dissipation: Hot spark plugs have a longer insulator nose and a shorter heat transfer path, which means they retain more heat within the combustion chamber. They are designed for engines that operate at lower temperatures or under lighter loads. Cold spark plugs have a shorter insulator nose and a longer heat transfer path, allowing them to dissipate heat more efficiently. They are used in engines that operate at higher temperatures or under heavy … Continue reading Difference Between Hot Spark Plug And Cold Spark Plug Explained
