Contour was bought in the NorthEast and is now in Las Vegas. Plug and wires need to be changed. Contour tends to run a little lean. No CEL's and fuel economy is running in the 23-24 mpg range with mostly city driving and lots of AC. I'va e always used motorcraft, but am open to ideas about a differetn brand. 97 Contour, ATX, Duratec with 218,000 miles.

Motorcraft is good, 23-24 mpg is good for a Duratec ATX. "Always do the cheap and easy ones first." 1996 V6 ATX 96K miles

I've always used Motorcraft. Batteries are designed for warm climates, I thought that maybe some brand of spark plugs have a better repuatation for being good in the heat.
