When is it a good time to change plugs?
That's a turbo charged engine for you. Although compared to my previous TC vehicles the lag is very minimal on my EcoBeast.That's what I was thinking, and heard a lot off ppl that torture this truck do first. My truck idles smooth and pulls great. I just hate the lag time.
However, due to the different metals between the spark plug (steel) and head (aluminum), it is best to "crack" the plugs every 20K to ensure they don't seize in the head, and don't build up a ton of carbon at the end of the threads near the electrode, that can break loose when the time to actually change the plugs come.I think Ford recommends 100k for sparkplug replacement.
