For a more long lasting improvement, put a 77070023 cold air intake on it. Throttle response gets better in all kinds of driving, and I have seen a 25HP gain at the rear wheels with just that one part change, above 5000rpm. I know alot of people say cold air intakes don't work, but that particular one is actually good.



Zippy.. Does the 77070023 cold air intake work on a 2005 hemi ram also ?
