Moab can be pretty dusty and depending on what type of air filter you have, I would recommend a pre-filter if you're running a CAI, I also recommend taking an extra air filter to have a nice clean one for the drive home.
I have a CAI with an oil filter but for Moab I run the non-oil version with a pre-filter, makes it easier to remove and clean each night. When it's time to go home I put the still clean oil filter back in and no worries.
If you didn't already know, you are on your own for any drinks and food during the trail runs so make sure you have a cooler and ice if needed, try to keep your tank full - fuel up at night or be sure to allow enough time in the morning. when they say you carry out everything you make...that means "everything" you make, makes you think about what you'll have for lunch :doh:
It's a lot of fun! I think I'm running Top of the World on Saturday as well. :beer:
