Hey guys first time owning an audi. Just recently bought a 2016 Audi A4 Quattro s line and I had some questions. I'm planning to do basic maintenance work but of course I'd like to upgrade some of the parts and my main question is. Is an apr or tune required? For now I was planning to change the turbo inlet hose and get the afe oem style filter. Coming from owning a Subaru and having the Cobb access Port I just want to make sure I don't break this thing to easily

 

Congratulations on your purchase and welcome aboard! I'm sure all your questions will be answered by many experts on here. Looking forward to some pictures.
