Frankly, I'm not convinced the CAI did anything other than increase intake noise, as it is much louder than the stock box. I've had CAI's before and never experienced this much intake noise tho; it might be due to the heat extractor vents in the hood but it is, none-the-less, much noisier.

The manufacturer is a high quality company & in their ads they claimed X HP/torque increase w/their tune & CAI. Mine didn't come close to the claim, instead coming in @ a much lower level, albeit one I had been told/read was more realistic. From that aspect, they were just about on the numbers.

Ford makes a strong claim to their intake box as being very efficient & I almost believe them. Perhaps you can pick up a few ponies up top but if you aren't racing the car, and I don't, is that of any value to you, especially @ the cost of a CAI?

I haven't dyno-tuned my car yet- that's next. We'll see if the CAI shows something of value in that venue.
