Understanding Spark Plug Heat Range - NGK Spark Plugs
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. For most vehicles, the factory recommended heat range is sufficient; however, on some modified or special-use ...
