    Comments about Autolite Racing Copper Core Non-Resistor Spark Plug:

    I was sent 6 of these plugs, and 2 Bosch Spark plugs. I don't know why this happened, but I ordered 8 Autolites, and should have received 8 of them, not 6 and then 2 random Spark plugs that I didn't want. Shipping dept screwed this up.
