Cold air intakes won't void your warrenty as long as ist doesn't cause a problem directly related to the intake.

A cold air intake usually adds "Few" extra ponies. Defintely one of the best bangs for your buck mod wise.

I'm not to familiar with the PZEV set you have (I have a ztech) maybe one of the other bobble-heads around here will know more. :P

Only difference between the regular and pzev motors, relating to the air box is a separate breather hose. FocusSport.com shows the difference: http://focussport.com/coolflo.htm
