5.0 Mustang & Super Fords magazine did a "Cold Air Shoot Out" in August of last year, where they tested 11 different C.A.I.'s on the same 2005 GT on the same day. The testing method and "rules" as outlined in the article were this:

"The same car will be used for all testing on the MD Motorsports chassis dyno. Rear-wheel horsepower will be measured in 100 percent stock form. The car will then be tuned to a set air/fuel ratio and set timing level. Each cold-air will be installed according to the manufacturer's instructions. Rear horsepower will again be measured with the cold-air in place with run conditions (coolant temperature, inlet-air temperature, timing, air/fuel ratio, and so on) as close as possible to the baseline pull. All efforts will be made to adjust the air/fuel ratio to the exact same as the baseline run to avoid this variable causing a change in horsepower. This testing procedure will be continued for all of the cold-air systems submitted for the story, which should ensure we have the same weather, car, testing facility, and tuning for equal comparisons."

There were some concerns and questions from some of the manufacturers, and the article continues for a couple paragraphs about how those were all addressed.

The summary of results:

Lowest Individual HP Gain: 17HP

Highest Individual HP Gain: 27.9HP


Lowest Individual Torque Gain: 14lb-ft

Highest Individual Torque Gain: 21.5lb-ft


Average HP Gain: 22.8HP

Average Torque Gain: 18.6lb-ft
