How can I improve the performance of my Ford S-Max engine?

I own a Ford S-Max and I've noticed that the engine lacks power and responsiveness. Are there any upgrades or modifications that I can do to improve its performance?

John, one way to improve your Ford S-Max engine's performance is to replace the air intake system with a cold air intake. This will allow your engine to breathe in cooler, denser air and increase horsepower.

Another option is to install a performance chip or tuner, which can optimize your engine's fuel and ignition timing for better performance.

I would also recommend upgrading the exhaust system with high-flow headers and a freer-flowing exhaust system. This will reduce backpressure and increase power output.
