so bought a 99 4.6 about 2 months ago has 106000 on it bought it cheap havent done much to it beside change the oil and put some zip ties on the throttle cable it was stretched a good 2 inches. i play out in the mud so with that in mind gonna upgrade/replace so things what maintenance should i do only thing i was told was replace were the brake booster what shocks do yall run plugs and so on
things i plan on doing
1-plugs+ wires
2 coil packs or should i wait til it goes?
3 its a auto gonna flush the tranny
4 tie rods where can i find greasable ends

also are there mods that would help with the lack of power that come with the 4.6?

 

Moog suspension parts are greasable.

And gotts mod will help a little with power, search this site and you'll find the how to for it.

 

never have bought into the high dollar plugs, and my results have been negligible. but a for a few bucks more, why not. some coil wires provide less resistance, and can increase effciency, just make sure they're properly supported and away from hot things. i think the tranny flush interval is somewhee around 100k anyhoo, so i'd do that. and pizzaman on the rest.
