    The standard Autolite plug has value

    Comments about Autolite Copper Spark Plug:

    Although most drivers will want a platinum plug able to last 100k in their cars, the standard old school copper core plug by Autolite is one of the best cost effective plugs you can buy for your old high performance hot rod. The lumpy cams and rich carburetors will tend to dirty or foul any plugs up in a season of cruise nights well before the plugs actually wear out. Therefore, it is senseless to buy expensive plugs.

      Comments about Autolite Copper Spark Plug:

      I've got 2 GMs and A Ford and they all use Autolite #26 plugs. I have beat the heck out of these plugs, pulled them and cleaned them up and kept going with no trouble. I ran the same set of Autolite Plugs in my Buick for 3 yrs before I changed them and they were still running good at the time I decided to change them. I ran the same set in my Chevy for 2 yrs then pulled em and cleaned them up and ran them some more untill I sold the car. Great Plugs Autolite. Thanks, and by the way the ones in the Ford are now 2 yrs old and still run great.
