Wow, before we moved up here I bought a set of Champion platinum plugs for the truck.

Had it at the shop today (no effin' start - another fuel pump?) and asked the mechanics if they'd install the plugs while under the hood.

They were pretty adamant about only using Motorcraft plugs. Said they made lots of money replacing other types. I told them to hold off on the plugs.

What's the skinny on "aftermarket" plugs and these engines?
