Hey everybody,
!st time on the forum, so wanted to say whats up. Got a 2004 w/ 4.0. put on a light bar w/ kc slim hi lites. Was wonderin if anyone else w/ lite bar had big change in gas mileage. Was gettin about 310-320 miles to a tank, now 250-265. I realize that the bar creates drag, but just curious. Also just changed the plugs. Used champion truck plugs (4412). Runs nice. anyone else using these or should I stick w NGK
