How to improve the performance of my Ford Focus?

I recently purchased a Ford Focus and I've noticed that the acceleration is not as smooth as I expected. Is there anything I can do to improve its performance?

One way to improve performance is to regularly check and replace air filters and spark plugs. These parts can get dirty and affect engine performance.

You can also try using a fuel system cleaner to help improve fuel efficiency and performance. Just make sure to use a reputable brand.
