How to enhance the performance of my Audi A1's engine?

I feel like my Audi A1's engine is not performing as efficiently as it used to. How can I enhance its performance?

Firstly, make sure you're using the right type of fuel for your car. Secondly, regular maintenance and tune-ups are crucial for optimal engine performance. Lastly, consider investing in performance upgrades or modifications for your engine.

Check your air filter regularly and replace it if it's dirty. A dirty air filter restricts air flow to the engine, decreasing its performance. Additionally, consider using a fuel injector cleaner to improve fuel efficiency and engine performance.
