I just got a 00 a4 1.8t AWD. I am thinking about putting a BOV on it? What type/kind/size of BOV should I get? Will putting a BOV on it cause serious harm to the car?? If so are there any alternatives to a BOV that wont cause harm?? Also what other kind of upgrades to yall recommend to do first to a stock 1.8 a4?? A cool air intake?? What are some LOW Cost (under a 200$ or so) upgrades I can do that will benefit the car or increase performance??? Thanks for your help!!
