How to increase the horsepower of a Ford Fiesta?

I have a Ford Fiesta and I'm looking to increase its horsepower. What are some recommended modifications and upgrades that I can make to achieve this? Any tips or warnings to keep in mind?

One of the easiest ways to increase horsepower on a Ford Fiesta is by installing a cold air intake. This allows for better airflow and can result in a noticeable increase in performance.

Upgrading the exhaust system is also a great way to boost horsepower. Look for a larger diameter and high-flow design for optimal results.

Another popular option is to add a performance chip or tuner. These can optimize the engine's settings and unlock extra horsepower.
