Are there ANY down falls to upgrading the air intake to like a AEM systems. I did a upgrade on my older YJ and that lead to other issues. Not serious but things continued to evolve on that projects before everything worked right.

 

be careful swapping the temp sensor & dont drive through lakes.

that's about all that comes to mind.

I have an AiRaid myself & those where the only things i noticed.

 

Ditto, and when he says don't drive through lakes, take that literally - you can safely ford water with a CAI, but you need to be way more careful than you'd need to be with, say, a snorkel.

I've been nothing but happy with my CAI, but if you can find a CAI that can also be converted to a snorkel system, you'd have the best of both worlds.

 

I have the KN cai and love it have had no problems at all. It does seem like the engine is a little louder now but thats about it.

 

I did my own from this thread and am very happy with it. Improved gas mileage and power.

I have been running the AEM on our jeep for about 11,000 miles and it works great
