does the versa has ignition coil and went you know is time to change the spark plugs and NGK are good spark plugs?

what the different in regular coil and plasma coil?

This engine uses four individual coils (solid-state ignition). The OEM spark plugs are iridium NGK plugs, and are good for something like 100,000 miles. I would suggest removing them at 30,000 miles to apply coating of anti-seize on the threads. Removing the plugs requires removal of the intake manifold and coil packs.
