How can I improve the horsepower of my Ford Focus?

I am a car enthusiast and I have been driving my Ford Focus for a while now. I love the design and handling of the car, but I feel like it could use a bit more power. I want to know if there are any modifications I can make to improve its horsepower.

One way to improve the horsepower of your Ford Focus is by installing a performance air intake system. This will allow for more air to flow into the engine, resulting in increased power.

Another option is to upgrade the exhaust system of your car. A high-flow exhaust will allow for better airflow and improve the horsepower of your Ford Focus.
