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

I recently bought a Ford Focus and have been having some issues with the performance of the engine. It seems to be struggling when accelerating and doesn't have the power it should. Does anyone have any suggestions on how I can improve the engine performance?

One way to improve the performance of your Ford Focus engine is to regularly maintain it. Make sure to change the oil and filter according to the recommended schedule.

You could also consider upgrading to a high-performance air intake and exhaust system, which can increase the engine's power and efficiency.
