How can I improve the performance of my Ford Galaxy engine?

I own a Ford Galaxy and I've noticed a decrease in the performance of my engine lately. What can I do to improve its performance and make it run smoother?

You can start by checking the air filter and replacing it if necessary. A clogged air filter can severely impact the performance of your engine.

Another factor that can affect engine performance is the quality of your fuel. Make sure you're using high-quality fuel and try adding a fuel cleaner to your tank.
