I run a CAI on my Cherokee and intake temps are consistantly about 40° F above ambient air tempreture. It's about perfect when it's 80-85° and crap when it's 10°.
FastPlastic made an interesting mod to his stock airbox to pull heat off of the manifold (I may have to go this route in the winter months or find a way to support my filter without the shroud).
