How can I improve the engine performance of my Ford Fiesta?

I recently purchased a Ford Fiesta and while I love the car, I feel like the engine performance could be better. Is there anything I can do to improve it?

One easy way to improve your engine performance is to regularly change your air filter. This will allow for better air flow and increase your car's horsepower.

Another way to boost performance is to use a higher grade of gasoline. Premium gasoline has a higher octane rating which can improve engine efficiency.

Consider upgrading to a cold air intake system. This can increase airflow, reduce intake temperature, and ultimately improve performance.
