There are some things to consider on the Rugged Ridge snorkel that have not been mentioned here. The biggest plus to me is the fact that it has a natural catch and drain. If your snorkel has a straight tube to the air box then anything in the snorkel ends up in the air box (mud and water). With the RR snorkel you can actually see how much it is catching and even clean it by pouring water into it if you so desire. I have the RR on my 12 and am very happy with it. Clearance is close but it clears my PSC light bar mounts. Take your time installing it. There were 2 things lacking in the directions. First off, the template did not work for me. That was ok because I was able to figure the cut out pretty easily. Second, you may very well have to remove some plastic from your air box base to fit their clamps on. I had to make a few extra holes in my airbox base to use the provided clamps. Fitment was tight and some massaging is required on the aluminum air tube. As stated earlier, I am very happy with it. I would NOT use the low intake though. My tires would just chuck water right into it.
In a perfect world there would be a snorkel like the River Raider expedition with a tubing and low spot system like the Rugged Ridge and replacing the side cowling rather than cutting the center cowling. If I had the time I would probably do a home made one setup like that.
