Carbon fouled Black, dry soot on the electrodes and insulator tip indicates a carbon-fouled plug. This can be caused by a dirty air filter, excessive driving at low speeds, too rich of a fuel/air mixture or idling your vehicle for too long.

Will a hotter spark plug stop fouling?
Rich air/fuel ratios require a hotter plug to prevent fouling. Mixtures that cause the plugs to read lean might contribute to preignition or detonation.
How do you stop carbon fouling spark plugs?
- Keep your engine properly tuned. - Make sure your air filter is clean. - Make sure your fuel injectors are clean. - Make sure your valve clearances are correct. - Make sure your spark plugs are properly gapped.
Why are my spark plugs fouling quickly?
Causes of a carbon-fouled spark plug include a dirty air filter, excessive driving at low speeds, too rich of a fuel/air mixture, dirty fuel injectors or idling your vehicle for too long.

How do I know if I need a hotter spark plug?
You can work out whether you need a hotter or colder plug by looking at the current ones. If the current plug is too hot then the tip may be melted or deformed. If the plug is too cold then you may have excessive build up (which can also be caused by burning oil or a rich air-fuel mixture).
How do I stop my spark plugs from fouling?
If you can't avoid a lot of idling or short trip driving, refer to the spark plug supplier's catalog for a spark plug that is one heat range HOTTER than the standard spark plugs specified for your engine. Increasing the heat range slightly can improve fouling resistance by helping the plugs run hotter.
Will a hotter spark plug stop oil fouling?
Rich air/fuel ratios require a hotter plug to prevent fouling. Mixtures that cause the plugs to read lean might contribute to preignition or detonation. 2.
What Causes Black Soot On Spark Plugs?
Can you use a hotter spark plug?
When making spark plug heat range changes, it is better to err on the side of too cold a plug. Running too cold a plug can only cause it to foul out, whereas running too hot a plug can cause severe engine damage.
What happens if I use a hotter spark plug?
These accumulated deposits can result in spark plug fouling, leading to misfire. If the tip temperature is higher than 1560°F, the spark plug will overheat which may cause the ceramic around the center electrode to blister and the electrodes to melt. This may lead to pre-ignition/detonation and expensive engine damage.

How do I stop my spark plugs fouling?
If you can't avoid a lot of idling or short trip driving, refer to the spark plug supplier's catalog for a spark plug that is one heat range HOTTER than the standard spark plugs specified for your engine. Increasing the heat range slightly can improve fouling resistance by helping the plugs run hotter.
What causes carbon fouled sparkplugs?
Carbon fouling is an indication of a rich air-fuel mixture, weak ignition, or improper heat range (too cold). Carbon deposits are conductive and can create a path for spark plug misfire.
