So anyone use the Autolite plugs? how are they compared to the Motorcraft plugs?

I got about 35,000 on my car. Still have the original plugs.

Why change them?

Cavero

A lot of people change them early before they have a chance to really seize in there

Just changed mine with about 47500 miles on the car. They actually looked better than yours. And THANK GOD it went pretty easily. I sprayed the Seafoam down into the well just like the TSB says and went about detailing my car. 30 min later I started pulling them one by one. half of them squeaked but only two scared me. The two that did, I just backed off 1/4 turn and then started pulling it out again and the seafoam got to the stuff and the rest was easy. Lots of blue smoke for the first 10 sec or so on first startup but after the penetrating fluid all burned off it was fine. Car runs a little better now!

What plug did you end up going with?

Cavero

Because I never got a reply I stuck with motorcraft. Never hurts to stay stock

Run a bottle of TECHRON SUPREME additive every six months and it will help cut down the carbon build up. Also it keeps the Fuel Card on your Sender clean so your fuel gauge won't go haywire! Ford Even Recommends it on the Diesels for the Fuel Card Issue!
