I was wondering when u can notice the engine misfiring and or when looking at them if there is a way u can tell if u need to replace them or not?

Thanks for all advice

 

Why wait ?? If they got some miles on them say 10k go for it replace them

 

yea my truck is sitting at like 36k right now

 

any idea how much the dealer charges?

 

any ford stealership charges and ridiculous amount and if they break some plugs yer lookin at some serious $$$...if u have any mechanical skills, save yourself a whole bunch of money and trouble and do it yourself

 

thanks for the info, im in iraq but about to go home, so it looks like im going to be changing them out lol

 

I'm going to change the spark plugs and the wires should I stick with motorcraft or go with another brand??
Any other brands recommended?? I'm all new to this stuff

Thanks for any information

 

Oh yeah stick with Motorcraft!! I had those expensive Bosch Platinum 4's in my old truck and they gave me problems. I replaced them with Motorcraft Platinums and had a lot better results. That's all i'll ever use now! It's a pain in the butt tho to replace the plugs on a V8.

 

I would love to replace my own plugs in this truck but scared to death I would have a couple break off in the head. I guess when its time I'll just fork over the cash and hope they cover to remove the broken plugs under my extended warranty.

I really think you could do it youself and save some money. I had to do half my plugs one weekend and the other half another weekend lol. All you need are a few different size extentions and small hands are a plus.

 

36k is nothing on today's spark plugs. They are designed to go 100k. My factory plugs were still serviceable when I pulled them at 84k but I changed them on general principle.

If you have a 06, it doesn't have plug wires unless it's a V-6.

 

Oh k i didnt know that, thanx for that info, so what is the spark plug connected to??

 

You have a COP (coil on plug) system. Each plug has its own coil pack that sits on top of the plug. If you have a 5.4, these are the 2 piece plugs that love to break when attempting to remove them, and there's a special technique required to change them.

 

lol what could that special technique be??
