    I've just been using Champion Truck Plugs . . . they seem to work pretty good.

      Not sure where i saw it and i havent tried it but ive read some good stuff about it...take the plugs you have and use a dremel and cut the part where the spark arcs across, only cut it back a teeny bit. this prob doesnt help at all...ill try to rustle up a picture...

        it's no problem to link to another forum. but if you start a thread for the sole purpose of linking to another forum for content, that's when we can see it as advertising and edit it.

        if you've noticed, people link to other forums all the time.

            I went with the tried and true Champions for the WJ. Champions is all I have ever used my entire life and probably the rest of my life.

            The plugs on my WJ had about 50K on them and were burned open to almost .055. I put the new Champions platinums in and gapped them to the proper setting, .035. Seat of the pants dino said I got a lot of ower back and maybe some more. I was not intending on buying plats, Advance Autoparts thought I had plats to begin with so I just went off that. I gained about 1.5 MPG from them as well. The new MPG numbers were higher than I had ever gotten from the Jeep. Next set going in the ZJ will definately be the plats.

            Not sure if your 99 has the coil pack or not, if it still has a cap and rotor then upgrading the coil, cap and rotor would be a good idea as well.

                Are they worth the extra cash you paid for them? What did they do to the performance of your engine?

                  I run the stupid carb 258. When the jeep gets a little rocky or off camber the 258 always had a flooding problem, I have upgraded to TFI coil and the splitefire plugs not sure which has improved, but the power and fuel mpg is up. One day I will good fuel injection. Just have to convince my BOSS (I mean my wife). When I pull the plugs they are clean with no carbon deposits.

                    I know its overkill for my application, but I went with Bosch platinum+4 plugs. They cost more, but there's no gapping or adjusting involved. Just stick 'em in and go. They've worked really well and are holding up nicely.
