First I would want to know why you want one. I have an air tube strictly to move my intake higher in the engine compartment for water crossings, a snorkel would work better but I don't like how they look. If you're doing this to increase power, forget it. There is no noticeable increase in power from a cold air intake, this from personal experience and backed up by Jeep magazine dyno tests. Plus the K&N filter has known issues in dusty environments, if you get one run a pre-filter over the filter. If you want to get noticeable power increase, get a good tuned header and cat-back, again from personal experience and Jeep mags dyno test this got the most bang for the buck.
