Temperature wise, the G3s/Injens/Stock should all be very similar as they are all sourcing air from the same place.

Very good counter response m4a1mustang....

I don't have a CAI...I was initially planning to get one, but after reading all of the posts here and dyno results, I totally changed my mind about it...In one thread, I recalled seeing similar results in reference to the CAI gains...Tony was right, most of the gains are seen at 7k and above....and like "Matt" said in another thread, I don't think any of us are planning to run our Z's at 7K plus majority of the time....

I just don't feel that the minimal gain of horsepower up top, is worth the loss of torque and power in the midrange....
