    It will look better but will not perform any better as the ECM will adjust, and you will be back to normal..........

    Not a problem. Performance or efficiency was not my primary goal, so nothing is lost. Heck, if I wanted performance, I would chuck the CAI idea and slap on a blower. I was mostly interested in uncluttering the engine compartment. Now, there may come some advantage when I pull the trigger soon on a Diablo 93 tune, combined with the E85 I use all the time now. But even if it still doesn't do anything, getting that weird, goofy looking intake tube out of there made me feel better. After all, isn't this also one of the reasons we do mods to our vehicles? To feel better about them?

    Yes, the Amsoil air filter is the one they sell that is reusable. Wanted a little better filtering, since my pickup is operated primarily on gravel roads and farm ground, without sacrificing air flow, and the ability to clean and reuse adds to the value.
    Hey there, VA, what do ya' say? How many vets did you kill today?

    Agreed that the aftermarkets look better. The factory design is mostly for noise control. If you think it's crazy looking though, you should look at other intake designs that have existed over the last 30 years. The ones GM sticks on the trucks now are very mild by comparison.

    Not really. It very much depends on how the ECM is adjusting. The ECM does not maintain a constant stoichiometric A/F ratio. It tries to attain that ratio, but it's constantly adjusting things based on close to a hundred variables. Not to mention all the external factors that can affect performance. On a chassis dyno, in a controlled environment, is the only way to know for certain whether it helped, or hurt, performance.

    However, as a CAI is a supporting mod, not a power adder, you're not going to see any real benefit yourself, without the necessary power adding mods.

The couple of tenths in 0-60 time picked up seems plausible. The MPG gain on the other hand, doesn't. I've had the Airiad MIT and filter in my truck for about 18 months now, and I've seen no significant MPG change.
    Correct, the video indicates "high speed accelerations" as I mentioned. I did not get better gas mileage when I added the CAI.

    Huh? No. The ECM is already programmed from the factory. And it won't give you the stoichiometric ratio every time. It will try to adjust fuel and timing to get that ratio. And more means more fuel, even if the ratio is the same. The A/F ratio is only a small part of what determines the efficiency, and power output, of an engine.

    A) Please learn how to use the quote feature of the forum when replying with quotes.

    B) No, that is not what you said. You said the efficiency nor power will change, because the A/F ratio won't change. That is simply wrong. The A/F ratio constantly changes, but the variation is indeed quite small. However, even with the A/F ratio remaining completely constant, more air means more fuel, means more power. Where that power is added along the RPM range of the engine, determines how it affects acceleration and MPG.

    Actually the Magnuson Moss Warranty Act says exactly the opposite.. GM(or the manufacturer) has to prove that the tune caused the failure.. They just cannot say it.. But Im sure most dealerships will say it until an educated vehicle owner knows the law. My dealership actually told me this.. GM has the technology to know what caused most failures.
