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

I recently purchased a Ford Fiesta and I love the car overall, but I feel like the engine could use some improvement. I'm not very knowledgeable about cars, so I'm looking for some advice on how I can improve the performance of my Ford Fiesta's engine.

The first thing you can do to improve your Ford Fiesta's engine performance is to get it regularly serviced. This will ensure that all the necessary components are functioning properly and can improve overall performance.

Consider upgrading your air intake system to allow more air into the engine, which can improve the combustion process and increase horsepower.

Invest in a quality performance chip or tune to adjust the engine's fuel and air mixture, leading to better performance and fuel efficiency.

Upgrade your exhaust system to allow more air to flow out of the engine, which can improve horsepower and overall performance.

Consider adding a cold air intake system to bring cooler air into the engine and improve combustion efficiency, leading to better performance.
