Product Description
The Dorman Spark Plug Non-Foulers are designed to help prevent spark plug fouling, particularly in engines that consume oil. These small adapters raise the spark plug slightly out of the combustion chamber, reducing its exposure to oil and carbon deposits that can cause misfires. Dorman is a reputable brand known for its extensive range of automotive repair solutions and problem-solving parts. While not a permanent fix for underlying engine issues, non-foulers can temporarily improve engine performance and reduce misfires.
