How do I increase the horsepower of my Ford S-Max engine?

I want to improve the performance of my Ford S-Max and I've heard that increasing the horsepower of the engine is the best way to do it. Can anyone provide tips or advice on how to do this?

One way to increase the horsepower of your Ford S-Max engine is by installing a performance air intake system, which allows for better air flow and thus more power.

Upgrading the exhaust system can also help increase horsepower, allowing for better exhaust flow and improved engine performance.

Don't forget to regularly check and change your air filter, as a dirty or clogged filter can decrease horsepower and overall engine performance.

Consider tuning the engine computer to optimize performance and increase horsepower. This should be done by a professional for best results.
