Hello. I have a 2002 4.7 4X2 4speed at 71k with mobil 1 himilage and kyb shocks on all 4. What is the first most common upgrade, or mod i should do to my D?
Well I got syn in the motor. I will have syn in the diffs, forced CAI, E3's in a year, aftermarket muffler at some point. thats my plan so far
Is there any tinkering I can do to the eng?
i hope you dont mean the E3 spark plugs, bc these engines run best with plain old, el cheapo copper core chamipions, or autolites in them, dont waste your money on the fancy "special" spark plugs, even with 3 tips you dont get more spark
