Default Autolite plugs

How long do Autolite copper plugs usually last? I heard that they don't last as long as the stock plugs.

If you can get at least 50k miles out of them for a decent price, sounds ok to me. Figure thats three years of driving or so

I change my autolites every 6 months (103'*), they will loose their gap long before 50k.

If there is such a thing as 102 they are way to cold for your car.

Autolite goes in reverse for coolness.

605 - 1step
104 - 2step
103 - 3step

I change mine about every 3. At 8 bucks for 6 and 15 min of labor i'm ok with it. If your modding your car, you should check the plugs once a month or so to make sure they are wearing ok and have the proper color. If your not modding your car, you dont need cooler plugs anyway.
