They are not completely not worth it, but they are expensive and only yeild a small increase in power. But I would never say a power making mod is not worth it. If you have done all the other basic mods, and dont want to step up to heads or cam, then go ahead and do the pulley, but concentrate on everything else before going to a pulley.
not worth the trouble and exspense for the gain (better wording ) and if you have an A4, it could discharge your battery at idle..then you need a smaller alternator pulley.....then you need a differnt belt..then you better buy two and carry one for a spare...then...........
