Hi i own a 94 passat glx vr6, and i just removed the air box and well it has like more strenght and it sounds really nice and deep and it sounds like if my engine had a turbo kit in it its sounds really nice, but by removing the air box will affect my car in a way? and the fuel economy?:banghead:

you still need an air filter... hopefully you have an air filter on it

well my car is running with out an air filter right now im planning to get a air intake thing so should i put it back u know the filter right away?

yeah, unless you want rocks and dirt getting into your engine
