How to prevent spark plug fouling in the Ford Galaxy?

I recently purchased a Ford Galaxy and have noticed that my spark plugs are getting fouled very quickly. I have tried different brands and heat ranges but nothing seems to make a difference. What can I do to prevent this issue?

You may want to try using a higher quality fuel filter to prevent debris from clogging your spark plugs. Also, make sure to properly gap your spark plugs before installation.

Regularly changing your oil and air filter can also help prevent spark plug fouling in the Ford Galaxy. Additionally, check for any vacuum leaks that may be causing an imbalance in your fuel mixture.

I had a similar issue with my Ford Galaxy and found that changing to a colder spark plug heat range helped reduce fouling. Also, make sure to regularly clean or replace your PCV valve.
