Spark Plugs and Wires
I went looking around on the forum for some information on the various "performance" spark plugs and wires and found quite a few strong opinions. I'm not expecting a HUGE increase in performance or MPG or anything like that.
I was wondering if anybody had any technical or dyno numbers that would confirm\deny the claims of the various brands.
I was reviewing the wires from the following vendors: Taylor, MSD, Granatelli, Bosch. (Are there other vendors that I should look at, not on the list?)
Furthermore, what about plugs? What brands and models are good? I hear time and time again that MotorCraft plugs are the way to go.
I don't want to start research into the technical differences between these wires and plugs when someone else might have already done this. Plus they might have tested them on a dyno.
I'd like to be able to collect samples to perform some honest sampling of the construction and electrical properties. Answer those questions about resistance. Provide some real comparison in a standardized fashion. Maybe I can find a shop with a Dyno willing to let me perform actual performance testing.

With my 2006 and the Xcharger I ran the Autolite 5143 or the NGK TR6 if the autolite wasn't available. No need to buy the expensive plugs, the cheap plugs work fine on the 4.0. I changed the plugs each spring only because I drove the car a LOT of miles during the year, and raced it on the weekends. The plugs were always in good enough shape to leave them in, but since they were out for inspection anyway and at $2 each it was just as easy to put the new plugs in each year.

We've always used NGK on our Project cars. Right now our '07 4.0L runs NGK Iridium IX Performance plugs. I don't really have any direct dyno charts to show you the difference with the plugs because we added an Airaid CAI at the same time. However, I can tell you she pulls stronger than ever and doesn't skip a beat.
This is the plug I would go with if you have a naturally aspirated 4.0L!
