My 97 Dakota SLT CC with 3.9L used to get 19 in town and 22 highway at
70MPH. It was generally stock except for the K&N homebrew cold air, Dynomax
muffler, 180 stat and the 3924 plugs. Traded it in for a 2000 Durango SLT
with the 5.9L, family grew. I' getting 16MPG city highway combo and 19
straight highway. The only thin done to it so far is K&N drop in filter,
tube on front of air box going past radiator, 180 stat and indexed 3924
plugs. Indexed plugs did not seem to make a whole lot of power differance
but it definately had a smoother idle. Next mod is the muffler, hopefully
the spintech's from GS Motorsports. Just my .02 cents.
