Spark Plug Non-Fouler
An automotive engine spark plug non fouler is a small device designed to prevent spark plug fouling, a condition where carbon deposits build up on the electrode of the spark plug, causing a weak or no spark, and making the engine misfire. The non fouler spark plug is typically made of metal and comes in a set of two. The outer shell of the non-fouler screws into the engine block, while the spark plug is screwed into the inner shell. The non-fouler increases the distance between the spark plug electrode and the combustion chamber, reducing the chance of fouling. When the spark plug begins to foul, the non-fouler provides additional space for the carbon deposits to accumulate, which allows the spark to continue to jump the gap. This helps to maintain a consistent spark and prevents the engine from misfiring. Non fouler for spark plugs are commonly used in older vehicles with high mileage or those that burn oil, which can lead to increased carbon deposits on the spark plugs.

When choosing a spark plug non-fouler, confirm the thread size of the spark plug (usually 14mm or 18mm) as well as the type of seat it has, whether gasket or tapered. From the remaining options, choose the non-fouler that fits your application as well as your budget.
