How to increase horsepower in a Ford Fiesta?

I am looking to increase the horsepower of my Ford Fiesta, any recommendations for aftermarket parts or tuning options?

Adding a cold air intake and a performance exhaust system can significantly increase horsepower. I've seen gains of up to 20hp with these upgrades. Just make sure to do your research and choose reputable brands.

If you're looking for a more budget-friendly option, you could also try reprogramming the ECU. This will optimize the engine's performance and improve horsepower. However, be cautious as this can sometimes affect your car's warranty.

Don't forget to regularly maintain your car as well. Keeping up with oil changes, spark plugs, and air filters can also improve horsepower and overall performance.
