Spark plug 1998 F-150 HELP!
 

Sup,

I am changing the spark plugs as we speak...

I think the guy at the dealer gave me the wrong spark plugs. I just pulled one out at the thread length is about 3/8" long. Well, on my new spark plugs they are about 9/16" long....

The part number is AGSF-22W-MF4 for the new spark plugs.

I checked on motorcraft.com and this is the right part number but how can the thread length be different?

I will post a pick in a minute...

EDIT: The old spark plug part number is AWSF22E... I think, maybe the guy before me put the wrong sprak plug in it????

Nevermined, I can use these plugs...

Sorry guys for making it seem like a big ordeal, but better safe than sorry I guess.
