the 5.2 and 5.9 look the same... go to a junkyard and you can pull a stock airbox for $10 tops, get an air filter and call it good. or if you want the little performance gain you can even make your own "cold" air intake with parts from an auto parts store it would prob cost around $60-$70. /thread

My 60$ K&N Warm Air Filter.

Warm because I Highly doubt it ever gets cold air where I live.

I put on a Rugged Ridge 4.0 cold air intake on my zj but i kept the lower half of the stock filter box and nestled the cone filter inside of the box...i also kept the vacuum type plastic intake hose that feeds the stock air filter box so it still feeds cold air well while driving. With an extension tube made from my original air filter box tube, the cone should be separated pretty well from engine/intake/manifold heat. This combo match with a rustys throttle body spacer has made some drastic changes. Havent had time to work with calculating fuel economy changes but, throttle response and end of gear power is definitely much better. Idle seems to be better as well. The combination is definitely working, makes it sounds like a v6 versus I6. Suction noise adds appeal to engine sound in my opinion, not obnoxious at all. Intake and spacer together was $200
