The Car has 60K miles on it. Since the Daughters got it out of State, I'm going to do a pre-emptive tune-up. Using Bosch COP Verses Ford COP it's under $100 Verses over $300 for a Tune-up. Has anyone else used the Bosch COP? They have the same one year warranty as the Fords. Plugs will be changed at the same time. 2012 Focus, 2.0 Engine.
