Cleaning and oiling the filter is easy. Why do you want a cai? They don't produce any significant power and look costly. I've done a few but only because it was a pre req for other modifications. Just like any other air intake if you ask me, but I am new to jeep so maybe there are ones I'm not aware of. But from a performance stand point, once they're hot, that's it (they don't have any superior function) from my experience.
