For the US model Ford Focus (2006), spark plugs are the only thing to replace. There are no spark plug wires. Ford recommends spark plug replacement at 100k miles.
About every 50,000 miles.
Wires and plugs constitute a tune-up. DO NOT gap the plugs, it will ruin the platinum coating.
Does a 2003 ford expedition have spark plugs?
