Hello everyone I was hoping I could get some feedback on upgrades to do on my 09 A4 2.0T. I bought it as CPO so it is under warranty and my upgrade potential is limited for a few years. If anyone has opinions on things I could do that would be awesome. I know very little more or less nothing about cars. I have been reading for some months on this site but was hoping to get a more personalized response. I was thinking of getting a K&N Typhoon for the sound signature I would get if anyone has input on this please share. If there is any other things I could do that wouldnt void my warranty I would appreciate input as I know really nothing and seem to have trouble finding information. Thank you.

apr carbon intake instead of the K&N

Everything can be removed
