Best plug to use for a 5.4L

[doopeej]

I own a 97 Expedition Eb with a 5.4L.I need to change the spark plugs and was wondering if someone had some input on a good plug to use.

Look on the emissions tag under the hood. It has a Ford part number.(Motorcraft). Use original equipment and you will be a lot happier. You can buy cheaper ones, but they don't last as long.

a lot of times, ford updates part numbers and stuff. but yea motorcraft is probably the best thing youre going to get for your truck. ive never had a bad motorcraft plug that i didnt drop first

Autolite.Ford does not make their sparkplugs,they are made who make Autolite spark plugs with the motorcraft name on them.
