How Can I Improve My Ford Fiesta's Engine Performance?

I recently purchased a Ford Fiesta and I noticed that the engine performance is lacking. What are some ways I can improve the engine's performance?

One way to improve your Ford Fiesta's engine performance is by regularly changing the spark plugs. This will ensure that your engine runs efficiently and produces more power. Also, consider using a high-quality fuel for better performance.

Another tip is to have your Fiesta's air filter checked and replaced if needed. A clean air filter allows for more air to flow into the engine, resulting in better performance. You can also invest in a cold air intake to further improve air flow.
