Do I need to replace spark plugs if they were replaced 6mos ago but I didn't replace the wires?
I replaced the spark plugs 6mos ago but I failed to replace the wires. Now I want to replace the wires but I'm wondering if I should replace the plugs again too.

no you don't have to. check your manual book, if you have it.
