How can I improve the performance of my Audi engine?

I recently purchased an Audi A4 and have noticed that the engine is not performing as well as I expected. How can I improve its performance?

One way to improve the performance of your Audi engine is by regularly servicing and maintaining it. This includes changing the oil and other fluids, as well as replacing any worn out parts.

Another way to improve engine performance is by using high-quality fuel and making sure your spark plugs are in good condition. These are often overlooked but can make a big difference.

You can also consider getting a performance chip or tuner installed, which can optimize your engine's performance and increase horsepower.
