    Comments about Autolite Copper Spark Plug:

    These work great as the Primary spark plug in my 2004 BMW R1100s. I have used other brands as well and these work just as well as anything else. I have 2 plugs per cylinder and use another brand as the secondary plug. The other brand in combination with the Autolite work very well.

      Comments about Autolite Copper Spark Plug:

      These plugs do the job for stock or performance. Somebody gave them a bad rating because they 'only' lasted 40,000 miles. You are supposed to change them at 30,000 miles so that is actually a positive review. Change the stars to 5. You can't beat them for a street driven Neon.

        Comments about Autolite Copper Spark Plug:

        My schedule recommends changing out plugs every 30 thousand miles. These autolights cheapos are fantastic. NGK were the ones installed at factory and Autolights far exceed there performance. I know they exceeded fuel milage since I bought this vehicle brand new and now with autolights get 2-3 miles more then original in city driving per gallon. Highway about 3 miles more then NGK

        • I Wouldn't Use

        Comments about Autolite Copper Spark Plug:

        These lasted less than 3 years and less than 40,000 miles used with the Autolite 97066 Spark Plug Wires. I bought the "Professional Grade" thinking they would last but they failed quickly.
