i have just installed my Induction Dynamics CAI on my 2001 cavalier LS 4dr today. this is a great product, a bit on the overpriced side but if u got the money then its straight. installation time was decent, although when i put the battery back in there was basically no room between the first coupler and the battery. but once i wiggled everything around a bit it all fit in nicely...... then it was time for a test run. i could actually tell a great difference between the ID CAI and my old Vibrant Performance short ram. throttle response seemed to be a little quicker, when i got up to about 45mph and stomped on it, the car was ready to go. overall i give this product a 8 out of 10 (a couple off for overpriced, ugh). love the stickers that come with it, lol. OH YEAUHHH.
