As Yuccahead stated, if you are planning any water crossings, they are probably a very bad idea. If you aren't, then you can probably get one for a price you like. Airaid, K&N, Mopar, Spectre and a host of others make kits for most Jeeps. There are also a number of snorkel options out there too which also bring in cold air and work and look great. The nice part of owning a Wrangler, there are like 40,000 companies out there making aftermarket parts for them.
