11 maj 2018 · This is a comparison of a cold heat range plug (left) versus a much hotter heat range plug (right). Notice how the distance between the ceramic and the spark plug shell on the hotter plug requires heat to travel a farther distance, which maintains more heat in the spark plug.
For a spark plug to function properly, it must have a tip temperature high enough to burn off carbon deposits (self-cleaning) and avoid fouling, while remaining low enough to avoid overheating the ceramic firing end and pre-ignition.
Choosing the Right Spark Plug. Using the correct heat range is key to getting the performance you want out of your engine. For most vehicles, the manufacturer-recommended spark plug and heat range is the best option. Consult your owner’s manual for the right spark plug for your car.
Very cold heat ranges such as C53CX spark plugs have modified (shortened) ground elec-trodes. This helps expose the spark to the mixture and protects against pre-ignition from an overheated ground electrode. J-Gap Projected Tip This gap style positions the spark an additional 1⁄8
1. Stay cool enough to avoid pre-ignition and/or electrode destruction. 2. Run hot enough to burn off combustion deposits that would otherwise collect at the firing tip. 3. Adapt to specific engine characteristics and widely varying driving/load conditions.
