I'm looking into getting a high flow cold air induction kit onto my 2006 Ram 4.7L 4x4. I have a "drop in" K&N air filter, but am interested in losing the box and installing a cold air kit. Here's my question...which is better in the first place? factory air box -vs- cold air kit? what are the advantages of each one? Does one offer more HP? more MPG?
Also....what are the best ones? K&N with the single pipe? the dual air filter that has the pipe that "T"s? Thanks so much guys for all your help! I love this forum!!!
