Hi all,
I'll admit, I'm a total newbie when it comes to CAI systems.
I have read conflicting reported about the effect that they have on gas mileage. Some say it helps to increase it, others said it decreased.

I know that many of you on this forum have them, so I'm curious what your experiences have been.

Thanks in advance,
Carlo

I put the K&N 63-6014 cold air intake on my Frontier. The thing it changes the most is my pressure on the accelerator pedal. The roar of the unrestrcted air into the throttle body is intoxicating. The truck springs forward with just a little pedal pressure.

With a little self control, I am sure I will be getting the same mileage as with the stock unit.

The one thing I have experienced when it comes to gas mileage is that quality gas gives me from 1 to 1.5 MPG more. I normally use Union 76 regular unleaded but recently used Valero regular. The drop was almost instantaneous. Only Union 76 from now on.

I agree with the above statement concerning the quality of gas used. I tto, have seen an increase with using Sunoco over Speedway!

I installed the AirAid Intake on my truck, and have seen an increase in gas mileage since the install. I also installed the Banks Monster Exhaust prior to installing the intake. After the exhaust install, my mileage actually dropped almost 1 mpg. This can probably be attributed to the thrill of the new exhaust sound! After the newness wore off, and I became accustome to the sound, gas mileage went back to where it was pre-exhaust. The Intake has since increased my MPG by 1-1.5 mpg. Again, this is with conservative driving! It would be very easy for me to tromp the gas every time I took off just to listen to the sound of the engine, but I know my gas mileage would go to pieces! The AirAid is fairly inexpensive and installation is super easy! They even provide all the necessay tools (aside from a screw driver). If I were to do it over again, I'd probably forego the exhaust and just do the intake, it was cheaper and seems to have had greater results. So, the combination of a free flowing intake, good quality fuel, and a light touch on the gas pedel should net you a decent increase in your fuel mileage!

I just installed the Airaid CAI on my truck 2 days ago. I've noticed the gas milage is actually about 1-1.5gpm better. But I did notice it seems to bit a bit more touchy. On the highway the MPG goes up very quickly and in traffic or drive in city conditions the gas MPG goes down very quickly. Before I had the intake installed these changes were very subtle. Everything still averages out to just under 17MPG.

The power on the other hand is very noticeable. I feel bad for my truck cause I beat it up at every light and on-ramp. I mostly get on it to hear the intake growl. Like outlnder said the sound is definately intoxicating :twisted:

You'll probably see your gas mileage stabilize again soon. I think the computer is adjusting to the added volume of air and relearning your driving habits. I noticed mine fluctuate more right after installing it, but now that it's been on there for a few weeks, it reacts more like it did before!
