Great replacement plugs for my 2001 Electraglide. Engine has been punched up to 95 cui. Will never run any high end spark plugs again.

When I was a youngster all the hot rods used to run autolite plugs because they very seldom fouled. So I'm hoping for the same for my Harley.

    Comments about Autolite Copper Spark Plug:

    I used these in my old cafe bike. After setting the proper gap, they seem to work great. I have to idea about the longevity of the plugs but I would expect it to be good.

      Comments about Autolite Copper Spark Plug:

      I used this in my 1997 Custom Harley Sportster. I didn't have time to buy one at the Harley shop, I decided to check the auto store. I found this part to be a perfect fit and works just as good as the Harley Brand but so much cheaper and convenient to buy from auto store. I never knew they had these for motorcycles. I would have shop there sooner if I'd known. Great product, fast start!! I give an AAA++

            A:

            I would recommend gapping the spark plug to what the manual calls for.
