plugs
Man it took a few tries to join this site.
Hi I just bought a 06 4x4 w a 5.4L it has 23,000 miles on it.
I have been reading about changing plugs on this board.
How often should they be changed? Will it get better milage?
Think I would go w the 1 piece Champs if they like to break off?
thanks

I have almost the same truck and I will be changing mine out around 25k. Got lucky and got a set of 8 Champion 7989 for about $7 each on a pricing error. I've done a lot of reading on the plug issue and those that have changed them before 30k have had nearly zero stick or break. After that the chances of having problems increase greatly. Good luck with whatever you decide.

From what i've heard the brisk plugs are junk and need to be replaced every 25k miles or so....

I don't think so..... Motorcraft are MULTI-PIECE plugs, and the Champion is the one piece plug. Russ
