I would like to give my Sport Trac more power. My wife hasn't even put 3,000 miles on it yet and it seems to be running well. It's just that it seems so underpowered compared to my Excursion. I realize that there is quite a difference in the motors but even my wife says it doesn't have enough guts and she is not at all a gearhead. Any suggestions? It's an 02 with the 4.0 and about 92k miles. I'd like to spend less than $1,000 and not destroy the fuel milage.

 

If you haven't already done so, start with a tune up. Also might want to try a K&N air filter.
