I have not yet installed a CAI on my 2500 hemi. When the temp is arround +7c or below, this truck is a bonus to drive, realy performs great with the colder air. With colder temp. durring cold canadian winters, Will the hemi take longer with a CAI to warm up in colder winter and will thier be a loss in perfrormance? In the -20C range, my truck use's twice the flue as I suspect most cars/trucks do.
