How can I improve the performance of my Audi A7's engine?

I've noticed that my Audi A7's engine doesn't seem to have the same power and acceleration it used to. What steps can I take to improve its performance?

One of the first things you can do is to regularly check and change your spark plugs. Worn out spark plugs can greatly affect your engine's performance.

Make sure you're using the recommended grade of motor oil for your Audi A7. Using the wrong grade can cause your engine to perform poorly.

Consider installing a performance air filter to improve air flow to your engine. This can help increase horsepower and torque.
