Gas Mileage 4.7 Ahhhh!
As everyone probably knows, the 4.7 ltr is a gas HOG! Has anyone had any good luck with air intakes or any other means to help out the gas mileage on these suckers? I probably average just under 14mpg!!!!

RE: Gas Mileage 4.7 Ahhhh!
I have a K&N CAI and true dual exhaust on my trucksand it did help with gas mileage.
Not alot but some, anything helps. The SRT-10 went from 9.5 to 11 and the HEMI went
from 14.2 to about 16. Not geting on it.

wow, my 05 4.7 with the 206 cam upgrade gets 20/22 on the higway and 17/18 around town with a heavy foot. 22 gallon tank and i get close to 400 miles. the thing that helped me out the most was tire pressure. the truck state psi should be 35, tire states max psi of 44 so i put it in the middle at 40. noticed a big difference right from the start.

Real ways to improve MPG
written with Rams in mind
but 80% or more applies equally well
to Dakotas:
https://dodgeforum.com/m_447500/tm.htm
Be warned: it is a long read
As a mid-sized pickup
it is a shame that the weight of 2nd and 3rd gen Dakotas
has gone up so much compared to the originals
and this hurts city MPG especially.
