A horsepower or two and slight gains in torque is what I have personally witnessed.
I noticed you are using the supercharged engine for your test. How does the N.A. fare?
How well an aftermarket CAI works usually comes down to two things.
How restrictive the original factory equiptment is, and how well the aftermarket intake was designed to flow.
That being said, the NeedsWings CAI on an automatic equipped Crossfire will cut nearly 1/2 sec. off its 1/4 mile ET's.
I don't know what that works out to be in Net H.P. But it's a significant performance increase.
