I am in the process of begining my next mod, trouble is I can only do one now, and the other probaly this fall.
So, if it were your truck, would you first install electric fans?
Or, longtube headers?

By the way its a 98 2wd with a 4.6.

 

E-fans if you get a set from the junk yard there like 30-40 bucks and its not that bad to install and i felt the biggest diff. from E-fan's as a mod to my truck. Long tubes are fun to but they take a lil time and there expsvive just my 2 cents on mods to my 97 2WD 4.6L

 

E-fans.
