well....i noticed two things....one is that when u open ur hood when finished with a drive and if u touch n e thing it burns.....after the cold intake, everything seemed just a little cooler, a little...ha, then u touch the intake hose...it`s like ice...!!!....and 2nd...the rpm seemed to pick up jus a little faster....and smother on the high end....not like before, u feel there`s not enough air going into the engine...
