Hello i am looking into buying a 2011 audi s4 titanium. I am however looking to add upgrades as soon as i get it.

1 thing i am going to do is add a better air intake, wondering if the stock intake is the best or if there are better ones.

2 i am going to program it or chip it, i dont know what the s4 works best with, hopefully you guys will help me out.

3 i see people post videos on youtube with a timer like gauge in there window which tells them there 0-60 time, i would like to get one of those but do not know what they are.
