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

I recently purchased a Ford Fiesta ST and I am looking to increase its horsepower. However, I am not sure where to start. Can anyone provide some tips or recommendations on how to achieve this?

One way to increase the horsepower of your Ford Fiesta ST is to install a performance air intake system. This will allow for better air flow into the engine, resulting in an increase in horsepower.

Another option is to upgrade the exhaust system. A high-performance exhaust will improve exhaust flow and increase horsepower.

You can also consider getting a performance tune for your Fiesta ST. This will optimize the engine's performance and can result in a noticeable increase in horsepower.
