Well i havent seen the numbers on the CTA but on the focus. The full length CAI does not reduce torque they just dont give low end torque. They give more higher end torque, The short Ram style which is what the CTA is provides the low end torque but not the the top end. Now assuming since both are zetecs the same should apply. However the Tours are diffrent in there RPM range so this may be the reason the CTA doesnt follow suit when compared to the Focus findings. Or at leasty thats my theroy on the tour.
