I'm at 60K miles on my 2004 EB AWD 4.6 SOHC and I'm going to be going through doing all of the standard maintenance I do at 60K on all of my vehicles. Belt change, Spark plug, spark plug wireset, fluid and filter change. I'm wondering which 'if any' is the most recommended spark plug for this engine? At worst I'll just put original equipment back in but wondering if there is a favored plug that runs well for this engine. I've looked around on the forum but didn't see a post for this though it likely exists somewhere in the wealth of information posted. Any help is sincerely appreciated!
