    I usually do it 75k-100k so you may want to do yours along with wires. Go for motorcraft plugs and wires, sometimes these engines of ours run a little funky and will run like crap with other brand name plugs

    Welcome to the Forum by the way

    the most i would run them is 100K and welcome.....
  5. Hey, mine are too! Hahahaha. 139,142 miles and never had a change! lol I'm getting em done soon though. I try (at least on my Dakota) to keep em around 50-75k. But that has a V8 and my dad usually gets the cheap ones too. So that doesn't help.

    a mechanic friend of mine told me if it runs good and idles fine leave them in ,they last a long time .....thanks
  7. They do. With almost 140k, I only have a slight miss in it. And that might not even be from the plugs. It could be an intake leak or something of the sort. So yeah, if she runs smooth.....don't mess with success haha
