Your civic qualifies for the 98-081 emissions warranty extension. If you have less than 150k on it you can get a free set of plugs, wires, cap and rotor plus an oil change at no cost ( assuming it hasnt been done already ) from any Honda dealership.

And, if under 150k, Honda will fix any DTC related failure on your car for free.
