How to increase the performance of my Audi A2's engine?

My Audi A2 seems to be lacking power and acceleration. I've tried using different fuel types and getting regular maintenance, but it still feels sluggish. What can I do to improve its performance?

First, check your air filter and make sure it's clean. A dirty air filter can restrict air flow and decrease engine performance. If it's dirty, replace it with a new one.

Another thing to consider is upgrading your spark plugs. Over time, spark plugs can become worn and cause misfires in the engine. Upgrading to high-performance spark plugs can improve engine performance.
