Spark Plugs anyone ?

Anybody change the spark plugs yet? Is it a DIY job? I have been reading about the plugs on older Ford 5.4 engines and the issues they have.

I've never done it, so I don't know if it's a relatively easy DIY kinda job. I would have to look at my BIL's truck to see. I do know that the spark plugs are a totally different design from the 5.4L and do not have the same issue with the bottoms of the plugs breaking off.

With that said, if you plan on doing it yourself, do remember that you have 16 plugs to change. Eight along the top and eight along the sides.

It looks to me like you might have to remove the fender liners to get at all of the lower plugs.

It's possible that no one has enough milage on their trucks to worry about this yet. I think the recommended change interval of 97,500 miles could be a problem. I know there are some who will feel its OK to follow that interval because the plugs will probably last that long, but will a steel plug in an aluminum head come out easily, and without causing damage, at that mileage?

Another thing is that when plugs wear, they demand more of the coils and put more stress on them. Maybe a 50,000 mile change interval would be more reasonable. I'd rather replace some $5.00 plugs every 50,000 miles than coils at $60.00 each when they burn out prematurely.
