What is the best way to increase the horsepower of a Ford Puma?

I have a 2002 Ford Puma and I am looking to increase its horsepower. What upgrades or modifications can I make to achieve this?

One way to increase horsepower in a Ford Puma is by installing a cold air intake. This allows for more air to flow into the engine, resulting in improved performance. Another option is to upgrade the exhaust system for better air flow and less restriction. Adding a performance chip can also give a boost in horsepower.

I have found that tuning the engine and changing the air/fuel ratio can also increase horsepower in a Ford Puma. Additionally, upgrading the spark plugs and ignition coils can help improve engine efficiency and power.
