just bought a 2000 audi a4 1.8t quattro last month 117k mi. so far no mods really, just a badgless grill, exhaust from the cat back. I am planning gettingapr tuned at waterfest this year. I would like to put in a cold air intake before i go, any suggestions? I do not know much about this car exceptthat its awsome.any suggestions on what mods first let me know!!!!

 

welcome, I would direct you to the newbie guide (click on the A4 section and scroll down not more than half a page)
