Gotta Love the Truck
 After Having my Titan for a while I will tell you this.  If you ever get tired of it,( not likely) just go and get yourself a cold air intake.  Nismo make the best one for that pickup.  And it'll save you a hundred bucks or so.  Easy install, and then you will rejuvenate that titan and you will remember how much fun it is to drive
