these numbers are all over the place, and suggests to me you had a dyno problem. A KN does not supply 140 lb of torque with no HP gain, nothing does. In fact, it has been shown that a stock vehicle can not gain from an aftermarket intake, unless you are using the incorrect stock element.
FWIW, that is the lowest stock HP dyno number I have ever seen. 260-280 is the typical range. So something is up with your measurements. I am just afraid somebody will get the wrong idea about KN, when we may just be seeing bad dyno technique.
i agree. something is just not right there... IF a K&N element only i assume, added 140 ft/lbs they wouldn't be able to keep them on the shelf!! something is just not right about the numbers... what kind of dyno is it? recent calibration??
