Champion 7989
For those of you who have replaced your plugs with the Champions, what are your reviews. Anyone have any signifiant mileage with those plugs? 50k? I'm debating on what to do. I don't have any problems now at 53k, but a plug change is on the horizion.

I went ahead and just replace with autolites. I already have the lise tool, so i cant seem to justifiy spending extra money on other plugs. If the 2 piece design is cheaper, then why not use it? It is not like i will have to buy the tool again.

yah, but has anyone put 50k+ on yet and removed to prove how simply their patented plug comes out with out breaking,
Here's my point of view. The problem with the plug/cyl head design, allows the plug's barrel to stick in the cyl head's bore from carbon build-up.
If you use the Ford two piece plug and the barrel sticks, you can still break loose the plug's thread which will indeed cause the crimp to stretch. Although the stretch has occurred with the threads broken loose you can now use carb cleaner to soak past the threads and help break-up the barrel's carbon to help remove the rest of the plug.
If the barrel sticks on the champion how will you break the threads loose to add carb cleaner to soak to the barrel? It's a one piece plug. Something has to give. They claim you can use up to 75 ft/lb torque in a video I watched. Where will it break after that? Look at the plug and find the thinnest part. If that plug breaks between the thread and socket flats, how will you remove the plug?
Think I'll stay with the two-piece plug.

limegt, i took my old stock plugs out after 49K miles with no problems and i feel that the reason why is i ran lucas fuel system cleaner which breaks up carbon deposits. I did this for a couple tanks before taking the plugs out and none broke. I also soaked the plugs in pb blaster for about 30 mins before taking them out. even with the champions, i will run the lucas for a few tanks before replacing them again. i actually run it in a tank about everyy 3K miles to keep everything clean.

Thanks for the reply's. 37k and no problems is good what I was looking for. I've been running some MMO in the gas for a while and I will get some Lucas and run some of that before I do the change. I think I'm gonna buy the Champions and the tool. I really like the truck and like the way it runs, but I don't want to go much past where I am now before I change the plugs. It's gonna have to cool off here in Mo. before I do it though. It's hot.

This would depend on who you ask but it is what I am going to put in my truck. In the next 5-10k miles.

I dont rack up the miles very quick, I only have 30,000 on my 2005 f-150.
I spoke with my local ford dealer about doing the plug change before i put many more miles on her. He said he'd be glad to do it but, recommended i dont worry about the miles if its running ok. He said they havent broken anymore plugs on higher mileage trucks versus lower mileage ones. He also said they have tried pulling the plugs cold, warm, and hot and it doesnt seem to matter that way either. He said again that he would do it but, if it were his he wouldnt bother until their was a reason to. He said when they break its no big deal with the tool extractor and that they have used the tool many times and it works well. I might be looking at the new truck in the next couple years so i decided to take his advice and save some money. Like many others i have read a million posts on the plug issue, many to get them out ASAP and some to do it when theres a reason to. Dont know which is really the way to go but glad that they have the tool when they do break.
