4.6L 3Vs built before 11/30/07 had HT spark plugs. Look at the build date on your driver's side valve cover - NOT the production date of the vehicle
Correct. The easy way to identify new and old style heads is that the old style heads use a BLACK COP while the new style use a BROWN COP.
Not entirely true. My car is an 08 with Black COPs and new style plugs. To make sure just pull one and compare. You can also call ford and give them your VIN. They will get you the part number of your spark plug.
Hmm .. This is the first I've ever heard about this ...
so again... lol does any1 have a 2008 with NEW cooler heat range spark plugs installed.. lol and if so any suggestion on them
Is there an over the (parts) counter one piece replacement for stock engines thats NOT Champion? I wouldnt put Champs in a lawn mower. If not, is there a special kind of anti seize to use or just w/e is on the shelf?
