Wires and plugs constitute a tune-up. DO NOT gap the plugs, it will ruin the platinum coating.

Changing spark plugs is relatively easy. Disconnect the batter and spark plug cables, and remove the old spark plugs. Next replace the spark plugs with new ones, reconnect the spark plug cables and battery.
According to the 2005 Ford Focus Owner Guide ( for North America ) Both the 2.0 and the 2.3 liter four cylinder engines have the spark plugs gapped at ( .051 inch , plus or minus .002 inch ) * so ( .049 to .053 inch ) confirm with the Vehicle Emission Control Information ( VECI ) decal located in the engine compartment ( it will show what type of spark plugs to use and the spark plug gap )
I would replace the spark plugs after 50K, the wires and plugs again at 100K.
It is moderately easy to change the spark plugs on a Liberty, although it is rather tricky because of the gap between the spark plugs.
