How can I increase the horsepower of my Ford Fiesta engine?

I recently purchased a Ford Fiesta and I'm looking to make some modifications to increase the horsepower of my engine. What are some recommended upgrades or techniques for achieving this?

One of the best ways to boost the horsepower of your Ford Fiesta engine is by installing a cold air intake. It increases the amount of cool, oxygen-rich air that flows into your engine, resulting in more powerful combustion and improved performance.

Another effective method for increasing horsepower is by adding a performance chip or tuner to your engine. These devices optimize your car's fuel and ignition settings, resulting in more power and torque.

Upgrading your exhaust system can also make a significant difference in horsepower. A high-performance exhaust allows for better flow of exhaust gases, resulting in increased power output.
