I bought my 2008 f50 v10 with 40k on i now have just over 62k, wondering when the plugs should get done? been told 2 different things.

 

The ford change interval is 100k miles but it's not a bad idea to do it early. Depending on when in 08 your truck was made it may already have the 1 piece plugs instead of the 2 piece that are prone to breaking while trying to remove them. If the plugs boots are brown that means you have the one piece plugs. Use motorcraft plugs.

 

If it were me,,, I would change them. I seriously doubt they were done before you got the 40k mile truck. It's also a 08, they have been in there for eight years. They might be rather tight since ford wouldn't have used anti-seize.
