You can look up the correct Motorcraft replacement part at www.motorcraft.com AutoZone sells them for about $4.60 each.

Changing Mobil 1 at 3K miles is like throwing away 1/2 of every bottle of Jack Daniel's. You're wasting up to at least half of it's useful life (depending on your driving patterns).

Thanks Steve. I am going with the Motorcraft FineWire.

In addition, zgendron stated:

"Also, you may want to research Spark Plugs in the Zetec Mainintance forum. It appears as if the 4 cylinder (Zetec) comes with 2 Double Plats and 2 Regular Plats from the factory. I would absolutely recommend sticking with service manual recommendations. If it came from the factory that way, there's probably a reason for it."

What's the deal with that?

Thanks
