I want to install new spark plugs . As you can see from the pics , I was able to completely remove one, but the other one is being stubborn and won’t come out . The metal thread is completely out which is great, but the actual spark plug is still intact. I used needle nose pliers to try and pull it out and even sprayed Wd40 to help loosen it. No dice. Any thoughts? I have a 2006 mustang GT. Thanks!!

 

There are no pics to see but, you have a few options.

If you haven't already tried to remove the rest, here's the ford recommended method (TSB) on how to remove them to reduce the potential for breakage.

After you get them out DO NOT replace them with the same garbage plug. You can either go with Champion 1 piece plugs PN 7989 or Ford's updated plug for the Mustang (Can't think of the part number right now). I don't trust the ford part number as it still appears to be a 2-piece plug. The only thing they did was add a couple of tack welds to crimp area.

I and most others went with the Champion plugs. I've had them in my car for over 80K miles now (replaced the OEM's at 10K back in 2009). I'm on my second set of Champions right now. Ford only recently released the updated plugs (last two years?) so who knows about the long term reliability with them.

 

Thanks a million. Would a pair of long needle nose pliers work instead? Or something like the pic below?

 

You can try but the tools were made for a reason. If the carbon on the spark plug tip is really thick, pliers won't get the pieces out. It cements the spark plug body to the head.

You can always buy the tool, use it, then resell it for what you paid for on e-bay or craigslist. You can also check if your local auto parts store has one they can rent to you.

 

Thanks. I just ordered the kit. Last question. Of the plugs I removed, there was a considerable amount of build up. Whats the best way to clean/remove all of that before installing the new plugs?

 

I printed that service bulletin out and keep it with the shop manual for my Navigator. Thank you for posting that up.


Good stuff.

 

Build up where?

Just use top tier fuel like Cheveron or Shell or the like. The detergents will help clean up the interior of the cylinder. You can also add a fuel system cleaner to the tank and/or seafoam (follow instructions).

 

Quite welcome Fastback. If you replace the ford 2-piece plugs with the Champion 7989 you won't have to worry about that issue i the future
