YES! Air filter! a new one will be worthless, after a few days on the playa. If you don't already know how to put em in, learn...it's easy. Disconnect your battery cables after you park...youd be surprised how much a dome light drains your battery over a week..opening and closing..and leaving open your door. The dust will never, ever really leave your car..but I love that instant playa smell everytime, I turn on the A/C. Reports are..as of last week, that the playa is hard packed..so not as much dust as prior years. Have a great Fucking time!!
anything worth doing is worth overdoing..
