What is the best way to improve the performance of a Ford Focus?

I noticed that my Ford Focus is not running as smoothly as it used to. What are some effective ways to enhance its performance?

One of the simplest ways to improve your Ford Focus's performance is by regularly changing your air filter. This will ensure that your engine is receiving cleaner air and improve its efficiency.

Another important factor for performance is the type of oil you use. Make sure to use the recommended oil type for your Ford Focus, and don't put off oil changes. Old, dirty oil can significantly affect your car's performance.

A tune-up is also crucial for maintaining good performance. This involves replacing spark plugs, ignition coils, and other parts that can wear down over time and affect your car's performance.
