What are some signs that your plugs are going bad? I
know the Nissan's are long overdue, so I bought a set
just to make sure, but I'm not too anal with that car
about scheduled maintainence, except maybe oil.
Got some new wires, too; anything else? How long
does your average plug last? I bought the car with 27K
on it, and it's got 72K right now, so the plugs are
roughly 50K, (unless they're from the factory

).
Thanks for the replies, and, yes, I'm a mechanical
dumbass, for the most part.
