another $30 home CAI
Maybe a dumb question, but how do you remove the air sensor from the stock intake? It's in some kind of harness and seems to be "glued" on to it. Do I just break the glue out or what?
Sorry again if it's a dumb question but I don't want to break anything.
Thanks!

I recently installed an aftermarket intake and came across your dilema as well. There is no glue stuck to the sensor. It is just a really tight fit. I first unplugged the harness from the sensor and used two really thin screw drivers (on opposite ends) to help pry out the sensor, just enough to allow me to pull it out by hand. If you are not going to re-use your stock intake tube, others have just cut their tube...Other than that I believe they do sell a special tool just for that particular part..

just for what its worth
CAI are actually less efficient at creating higher MPG
believe it or not, and i have test on 3 turbochagred cars and one NA car, HOT air aids with better burn, since the hoptter the air the easier combustion, and more thorough combustion.
GRANTED you WILL loose a little power, BUT the MPG gain might be worth it. I havent taken delivery of my 08, but i will next week and i will doing it with the new JK as well to see.
but, as a rule of thumb, cooler air will yeild more HP but less overall MPG, hotter air will yeild less power but more MPG

If your engine yields more HP with a CAI it's because it's operating more efficiently (I think). Doesn't it make sense that you'd need less fuel (and air) for any given required amount of HP?
more HP is achieved by bringing more air in at a colder, denser temperature. By doing this your AFM compensates for the increased air by adding more fuel the moajority of the time, unless your car is just pig rich.
by doing this you actually consume more gas, but because of hte small increase of power, it takes less effort for hte car to move, and navigate. Thus giving you slightly higher gas mileage.
With a HOT air intake as per say. you are STILL getting MORE airflow, but it is not as dense as the cold air charge, thus bringing more air that is more easilly combustable into the chambers mixing with the normal prescribed amount fuel the engine would give with a more COMPLETE burn, just with no major increase in HP.
its a tradeoff. I personally am not a gas mileage weenie. My drift wagon gets 5MPG with a 17 gallon tank.
I just did it to see if it would work on a bunch of my cars, then reverted to my old setups after i figured it out

Here are some finished pics showing the air flow sensor. I'm also tossing in a pic of the program i run on my Windows Mobile phone to track mileage....I don't know, it seems like my mileage has improved a hair or 2.

The filter is attached to the tube once it goes through the stock box top, then you attach the tube to the throttle body. Once that's attached you carefully push the filter with the top into the box and clip it shut. I added a little bit of the pipe insulation I was going to use around the top of the trash can around the intake to try and mimic the effect of adding one of those diesel foam pieces, forcing it to breath out of the hood gap a little more. I don't think that's working so well.

I apologize for the fuzziness of the screen shot, something happened to it when I saved it as a jpeg. Granted, I haven't seen a huge increase...but hey, any little bit helps. I'm seeing a gain of about 1.5'ish mpg. I am an avid tach watcher....try to keep the rpm's 2000 or less. You'll notice I had a run of 13 mpg's...that was before I started watching the rpm's...so driving habits have a lot to do with it.
