hey everyone my trucks got 101,000 miles on it and have all the stuff to change the plugs but am just waiting till I have time todo it but anyways what did you all get for results after you changed the plugs?
I seem to be low on power

 

Is it a 5.4? Before I had mine done at 74000, I couldn't go over 3000-4000rpms because it would miss like crazy. Now, runs great and pulls hard. No missing anymore. Also, mine had no electrode left on the plug so I'm surprised mine ran at all... 4 of mine broke

 

I change mine at 90 k on my 2008 kr 5.4 and did notice a difference

 

yah sorry about that it's a 5.4 and that's what I was hoping to hear same thing it won't rev above 3,500 but isn't throwing any codes.

 

Mine were replaced with the champions. Some say stick with motorcraft plugs but I haven't had a problem with the champions. In my opinion at 101k miles its beyond due.. and more than likely the plugs will fix your problem since it was similar to mine. Keep us posted on how it goes. And best of luck to you with the plug change. I'm guessing you have the removal tool right? If not, get it before you start!

 

oh yah I have the tool not takin any chances and if you did it our self how long did it take you

 

I had a local mechanic do it. Took mine like 6 hours I believe. Luckily only 4 broke... I wasn't going to deal with it lol

 

I did it myself, none broke, took about 1 hour. The BAck passenger one was some problems but didnt break

 

yah that back passenger side plug looks like a pain to get to. any tips for success

 

I have a V6 and my plugs were not that hard to change. Why are the V8 folks always complaining about plug changes? Are they that much different? Someone please explain.
