Should I go ahead and change the plugs? I have read about the horror stories hear, and I dread doing it. Also can someone please give me a link or insite for a TSB on this. I did a search but every plug thread as those three letters. Also I was on the MAC truck today and he had a removal tool set for these plugs, is it worth my money to go ahead and buy it? I work on diesels for a living and hate working on gas burners but im not paying the dealership for something I can **hopefully** do without breaking them. Please help as im sure I need to go ahead and attempt this.....

I'm planing on doing my recently purchased 06 with 26,000 on it . I can't believe the price for a plug.

 

The latest version is TSB 08-1-9 and can be found here:

I did my '06 FX4 a couple weeks ago at 49k miles following that TSB to the letter. Four came out easy, but the rest were very tight and I was sure they were going to break. All of them came out in one piece
The back & forth method they write about worked good for me. Since I don't need my truck as a daily driver, I could afford to wait a week to order the tool if I needed it. I would have ordered the Lisle tool if I had to, but ended up saving myself $67 or so. I put in the Champion 7989 plugs and all is well ($12.99 each from Summit).

 

IMO, if you've got over 30K miles, you're gonna break at least one upon removal. I've tried most every trick and way I know, following the TSB to the letter, and I'm about 50/50 on getting them out successfully.

 

Did you use the double platinum plug? Also did you use some sort of anti seize when installing them.?

 

The Champion is a double platinum plug. I coated the electrode sleeve with nickel anti-seize, and in spite of the TSB saying not to do it, I put a small amount on the threads as well. I may be alone but I just don't like bare aluminum threads mated with steel threads without some kind of protection.

 

i wouldn't bother changing them, i've got 87k and im gonna let someone else deal w/it at 100k IMO

 

Ok, here's my view on the issue.


The plugs last 100K plus no problem.
- (I changed mine at 110k and got no engine performance or gas mileage increase, and the plugs looked good enough)

Yes, some of the plugs will Break when you pull them. It will cost you a few hundred bucks, but they've got the procedure down to get them out without much trouble.

Personally, I'd run them to 100k as ford recommends.

But I wouldn't worry about it at all, again, they've got the removal procedure Down....

 

I'm not going to wait until 100,000 miles to have mine changed.

 

I've got 60k and I agree on waiting til 100k. There's no guarantee all is well even on the low mileage ones. Besides, I could loose a tranny, etc., in which case I'll dump the truck anyway. Just my 2cents.

 

TSB 08-1-9 is no longer the latest version. I don't know where you can download the entire TSB, but you should refer to TSB 08-7-6. http://www.brokensparkplug.com/TSB_08-7-6_Pg1.pdf
