What are the best ways to improve the performance of a Ford Fiesta?

I've been driving my Ford Fiesta for a few years now and I've noticed that it's starting to feel sluggish. What can I do to make it drive like new again?

One way to improve the performance of your Ford Fiesta is by regularly changing the air filter. A clogged air filter can decrease engine performance and fuel efficiency.

You can also consider upgrading the spark plugs to high-performance ones. This can improve the ignition system and result in better overall engine performance.

Another tip is to keep your tires properly inflated. This can improve handling and fuel efficiency, resulting in a smoother and more responsive ride.
