How can I improve my Ford S-Max's engine performance?

My Ford S-Max's engine seems to be lacking power and responsiveness. What can I do to improve its performance?

First, I recommend checking your air filter and replacing it if it's dirty. A clogged air filter can restrict airflow to the engine, reducing performance.

Another way to improve your engine's performance is by regularly changing the spark plugs. Worn out spark plugs can cause misfires and decrease power.

Consider getting your engine tuned by a professional. They can optimize the engine's performance and improve fuel efficiency.
