Default Spark Plugs - 06 5.4L

Is it really as bad as I am told it is to replace the plugs in these things. It has 130,000 Km on it and it feels like it needs them changed. If it is as bad as it is made out to be does anyone have any tips or tricks to doing it and is there any special tools I should get to do the job?

Here is a link to Ford's Technical bulletin.

Let them soak a long time. Overnight at least. Loosen them slowly. I used alot of oil, and didn't worry about the hydro-lock. Just crank the engine over to blow out all the excess oil. (be sure that the plug wire ends are not too close to a ground source, or you'll flash off the oil mist as it comes out. (Very pretty)
My '06 model has only 50K, and I used this procedure, but still 2 broke.

I am guessing by that statement it is going to be difficult. Any tips to making it easier? I have only had this truck a few months and I have no idea what was done to it, but I dont beleive I had much attention so I dont think they would have ever changed the plugs. Do these engines still have the problem where they pop the plugs out sometimes or has Ford corrected that by my year. Do I have to worry about that if I change them?

Thanks for the info. Just out of curiosity I am going to call a couple of my local dealers to see what they are charging. If its outrageous I will just buy the tool and buckle down and take my time and do them. I will just make sure I soak them really well before and during removal.

got two quotes to do them at dealerships. One is a base rate of $375 plus half an hour labour to remove each one that brakes which is $51.50. Second dealer said $399.00 base rate no extra charge as long as no more than two brake. I will probably just do them my self, just take my time and spray them good while they are coming out.

I got quoted $450 but no mention of any breakage consequenses. They quoted me $20/plug and claimed they were iridium but I can only find platinum. http://www.sparkplugs.com/results_ap...1&AAIA=1422751

Default Plug Removal

Dukester - from personal experience, I would follow GatorB8's advice. Run Seafoam or Gummout (you need 1 1/2 bottles and it was on sale, so that's what I used) for at least one tank full. Next, warm the engine per the Ford Removal protocol. Then, disconnect the +battery terminal and remove the computer/mount bracket for better access. Loosen the plugs and use yer favorite penetrating oil and follow the steps laid out by Ford. If they break, and chances are that they won't, then go buy the tool. Use the Autolite HT1 plugs.

why does everyone insist on changing plugs at 50, 60k and so on when they are a 100k plug?

The only reason I can think of is better chance to not break them.

This only applies to DIYers though.

If you are going to pay someone to do them then I don't see a point in having them done early either.

I'm still on the fence with 63K on my truck. I will probably pay someone. This doesn't seem like a good truck for a beginner to learn with...
