People who say they can't tell a difference, don't pay attention to how their vehicle operates in ALL conditions! Anyway,all I can say is im VERY pleased with it! The biggest difference for my vehicle is greatly improved throttle response (which is what I was looking for) and a little added torque. I can really tell a difference on power robbing hills also! I've known about K&N filters since the 70's80's and cannot believe I haven't used on until now! What a dummy! K&N for life! My vehicle is a 2003 CADILLAC Cts,base model. I may have to get the cold air intake next!
