just so you guys know A cold air intake is a top end modification and it will lessen your acceloration off the line for several reasons the biggest being air velocity the air moves slower throught the larger pipe thus a loss of low end torque the air dosent get crammed in there at low rpm like it dose in a stock intake
but you will notice higher top speeds and better mpg on the highway you would be better off drilling 1" holes in the bottom of the air box or the side facing the inner fender
and using a K&N drop in replacement and when you open the intake you will notice more gains if you open the exhaust too . 
No where in your post are you comparing the CAI to vehicals with stock exahust systems...maybe you should have made your post a little more clear.....
Someone i talked to in NECO about the GMk when i was doing research about it, told me theres no lose on the duratecs with stock exahust...but some cars do posts losses, the duratec is not one of them.
Though i am inclined to agree with you, that some motors, a CAI will post a lower torque gain or even a slight loss, but the duratec is not one of thoes motors....
