I just bought some OEM plugs and wires off ebay. The wires, 748UU, are coming from "original auto parts xpress" and the 41-985s from a private individual. Research seemed to indicate that the 748UU are better quality than the 9748UU wires. It's tough to find the old 41-985s for a decent price, they've been superceded by a newer PN#.

With that many miles on the original plugs and wires, you should see a difference. I'm not sure if your model has a fuel filter or not, if it does then add that to the list.

That's great news. I'm sure you have a few scraped knuckles. You have warned you that it helps to have a few beers before you change the plugs and a few more after. Did you change the wires too?

Other than #8 it's all easy going. Also, once you're done, you don't have to worry about it for another 100K miles, so it's not like you need to change them twice a year, or something.
