What is the most efficient way to change Audi A5 spark plugs?

I recently purchased a used Audi A5 and noticed it has been a few years since the spark plugs were changed. I want to do it myself, but I am not sure where to start. Can someone provide a detailed guide or tips on the best method to change the spark plugs in an Audi A5?

The most efficient way to change spark plugs in an Audi A5 is to first locate the plug gaps and the materials needed for removal. After removing the old plugs, use a gap tool to ensure the proper distance between the electrodes. Finally, carefully install the new plugs and tighten them with a torque wrench.
