Logically, there should be no improvement by going to a cold air package or K&N filter on a 4.8, 5.3 or 6.0L engine....

I know talking to some people on our 06 Trailblazer SS that is pretty much what they have said too. That the induction system is so direct that you gain very little if anything by putting in the CAI. They say the gains you get don't offset the cost of the kits.
