I found the numbers from my dyno pulls comparing the K&N cold air kit to the stock box if anyone is interested.

Another consideration is that on the dyno you CANNOT get the same airflow into the front of the truck or into the CAI that you get when you are actually driving the vehicle. So a dyno is not the best place to do a performance comparison for a CAI.FerrariTruck said:Dont throw away your k&n just yet guys...when you do comparisons like that you dont get accurate dyno nums right away when you place a mod on there. It usually takes some miles to allow the pcm to compensate for the new mod. For example if you been running with the stock filter and box since it was new, the pcm has adjusted the fuel trim to the correct amount of a/f ratio for its state. however when you intially bolt up ur new CAI, you dramitically flow more air than stock. Intially this causes the motor to run a lean for a while until the pcm compensates with fuel for the extra airflow. It isnt until then that the engine is able to make more power.
mosrt10 said:VP2933 is completely right. There is many real world variables which have too be taken in to account before ruling out the cai. There is really no way I can think of to simulate 70mph air flow into a cai on a chassis dyno.:burnout:
