Just traded up to a 2002 B4000 - have questions

[aaaaaa]

I just traded my 99 B3000 in on a 02 B4000 w/ 4wd and have a few questions.

1) What bulbs do I need to get for the factory fog lights? Or are they self-contained?

2) Will performance headers make a noticeable difference in gas mileage?

Thanks!

From what I've found out, headers will do nothing for your (our) pitiful mileage. In fact from what I've read on this site and others, there isn't much that can be done that provides any noticeable improvement in either mileage or performance... unless you start dropping SERIOUS dollars.

My first mod was going to be exhaust, but I think I'll be better off with a good tune.

Even so, the 4 liter is no slouch stock
