Default Re: best spark plugs and wires to get?

just bought my ranger. it has double platinum plugs. the wires say carquest 8mm. the PO says they were changed "a few years ago" and it hasn't been driven a whole lot the past year. so, I suspect they haven't more than 10-20K on them.

the plugs look fine. how can you tell when wires are needing replacement, other than to wait till it starts running like shit? is there anyway to gauge how wel they are performing without fancy equipment?
