I run copper champion by the way in my 97 grand 4.0. If you do clean your plugs how do you do it ?
I know just buy new ones their cheap as I did but the old ones looked great so I just sprayed them with carb. cleaner and reinstalled with new crush washers.


Thank, 3

have not done that since the 1970 80's... sand blasters - ohm checks, its been awhile showing my age,

Being in the trade and dealing with 100$ an hour labor rates and the new 'forever' iridium* type plugs not cost feasible to clean.

I've done it on my 4.0 and others over the years. There is a little tool made for it that is essentially a thin file, but not as aggressive as a real file. Kind of like one of those metal fingernail files. All my tools were stolen several years ago and the ancient hand-me-down spark plug tool I had was lost. I use fine sandpaper / emery cloth. All you're worried about is the end of the electrode and the area on the ground bar across from it. Well, unless you have oil & gunk buildup or carbon bridging.

If the engine is running fine and it has no issues, you shouldn't really need to do anything before it's time to replace the spark plugs.

Lol HL and nobody here to clean my plugs for me either!

I used to clean my spark plugs just using some fine emery cloth on the electrodes then spraying them down with carb cleaner.

For quite a while I was using my bench grinder with med wire wheel for cleaning the electrodes. But this darkened the ceramic insulator. I heard this could be a fine metal coating, bad idea, so quit using this method.

I'm at the point if pulling the plugs they're getting replaced. Even though I have a set of new copper Champions I bought a set of NGK copper plugs which look like better quality. Hope to install them soon on my 96 4.0.

BTW, I use a non-seize stick on the plug threads and a real thin coating of dielectric grease on the outside of the ceramic insulator when installing new plugs.

You won't be disappointed. I replaced Champion copper plugs with NGK BKR6E on my niner. They are really good compared to the factory- spec. Champions.
