Nope. I ran the Airaid CAI with the poly based tube. Nice try though.

 

I have found that farting in the YES fabric gives you the same result as a CAI or TB spacer

 

The only problems I've heard about CAI's is they lose HP in the low end and add it to the high end. Soooo I guess that means good for the freeway and bad for the trails.

I can't imagine how a cai would make an engine run rich (too much fuel compared to the air coming in). If anything it would run lean. Since there is less restriction more air would be coming in than the computer would be expecting.

 

Here is a good read "Great Intake Face-off"....some testing the LX forum did on CAI's on the 5.7L Hemi using a dyno and track results comparing several CAI's and Stock box and filter.

Conclusion:

Simply put, the results in the test above....showed that stock intakes are every bit as good as any aftermarket intake tested.

 

I have this intake and love it! The sound and the power gain was incredible. But......did stall out after going too fast through some water. Did I mention the sound was great!!!?

 

I dont know how a CAI could make an engine run rich either but it sure made my engine run rich. Apparently there isn't a Mass Air Flow sensor on our JK's? I figure the computer started ramping up fuel output to compensate for the increased airflow and voila engine running rich. In all honesty I didn't notice any power increase, all I got out of it was the throaty sound starting at about 2200 RPM and that damn whistling noise.

 

this is a classic argument that ive done alot of reading about. Just to throw my 2 cents in. I decided to forget the hype and make my own descion. I did not go with a CAI becuase i do wheel and i go through ALOT of water but i did not have the funds for a snorkel so instead i wentr with a K and N filter and bought the cleaning kit. I have put 22,000 miles on the air filter and have cleaned it out after every 2 runs so it has def paid for its self there in the fact is reusable but i DID and will argue till im blue int he face gain 1.5 MPG after installing it. And i can always tell when it needs cleaned becasue my milage will go down. I have 35's on steel softys and 4.10 gears and going down the interstate i get a little over 18 mpg. No i did not buy my jeep for gas mileage im jsut saying i think you can get a better value out of a reusable filter then a cold air intake. Some will argue the OIL when you clean it can cause problems with your engine but i have had none so far. Just throwing it out there. Best part is when i do get a snorkel i will still be able to use the filter.

 

I never thought of that. There is only a Intake temp sensor not a MAS, I wonder why. You would still think that the 4 o2 sensors would be able to detect a rich or a lean condition but we know that is not the case. Hypertech even says that with their programming if you run a CAI it will run lean... once again the o2 sensors should adjust. Either way it looks like it is better to leave it stock or use a snorkel.

 

Running rich is generally a symptom of the AIT behaving in a manner that the air temperature is warmer than measured at the sensor. The more typical issue is leaning out and often times can't be easily remedied.

 

Well......I did put on an Airaid CAI and I know I gained more poop. As well as gaining a little over 1 mpg too.
