So I changed my plugs last night with the updated motorcraft sp 530 plugs, and guess what?? My car already had the exact same plugs in it. So they should have updated the 2014 owners manual.
I have to agree with ptjones...the old plugs looked like they still had a lot of life left in them and the gap was looking good as well.
I just thought after 101 500 ml it would be a good time to change them. Good thing they last that long, because it's a hassle to get to them. (air-filter assembly has to get off)
