reason to put on a snorkel

do they have kits for like carbs for snorkels? i guess i havent done too much research besides looking at the ARB ones (a bit pricey!?) for newer FI jeeps. im not sure i would actually need one cause if i got my jeep up the the intake in water which is about shoulder level or so, i think id have a few other problems. but i must admit i think they look awesome and would still get one!
