Cold air intakes worth the $$$ ?
Just need some advice on Cold Air Intake systems....i was told it is pointless in even purchasing and installing an CAI since it has no significant HP gains and would be a waste of money! I'm not looking for anything cheap..i want the best! 
I have 2004 V6 3.9L engine and was also curious if CAI for a 3.8L would be the same for the 3.9L. My buddy wants to get me K&N CAI but i'm really hesitant at this point and figured some of you guys could steer me in the right direction.
thanks

^I heard they upped the displacement on the 3.8 to a 3.9, not sure which year though.
As for the CAI, a K&N is one of the better units available, but JLT is probably a bit better, a CAI won't really give you power gains so much as a bit more sound and noticeably better throttle response. A 3.8 kit should fit your 3.9-it's the same engine as far as I know, just a bit bigger, I'd e-mail the manufacturer to confirm though.

Hmmm....?
This is what i jus found on another site:
"I work for Ford and they sent us a special memo stating that it had blah.blah.blah reasons for making 3.9L but none of the reasons had any performance benefits. All of the Ford plants in the world have assembly lines that with a few clicks of a button can produce any vehicle in the Ford lineup...kinda cool! Basically it is easier and more cost effective to run the 3.9L in the Freestar AND Mustang instead of 3.9L Freestar and 3.8L Mustang...especially since they are basically putting the explorer v6 in it next year. a temporary solution for production issues between vehicles."
