Same as. I was thinking of buying an afe cold air intake but didn't know the difference between stage I and stage 2 (apart from the cost), I guess the later stage two, is of improved performance, but is it worth the extra cost? Also is one louder than the other. I want a good sound but not to loud when on the motorway. I did e-mail afe directly to find out the facts
but had no reply. Any comments greatly received.
