Re: ??? about spark plugs
I've used a kit like that. They are good, but you don't get really any better performance. The better caps and rotors seem to last longer, esp if you take the truck/live near the ocean where salt tends to kill caps and rotors. In my mind, wires are wires so long as they can stand up to header heat. But, if you have the money you might as well just go for the upgraded parts, it is not much more than stock parts.
However, I have used those plugs and liked them. I pulled them out of my truck after 20 k to see what they looked like, and there were fine. The truck might have ran slightly better when i installed the plugs, a little smoother. But i did the cap, rotor, exc at the same time and just replacing old parts might have also made the improvement.
But to sum all that up, i would go with the better parts. I have on a few cars/trucks, and i don't see any reason why you should not.
