    Be careful
    I recently changed to this plug for my 2015 cvo limited. The engine does not start on first try like it does with OEM plugs. If you buy these and have the same issue, consider going back to the original plug.

    Original plugs in a 2012 FXDWG. Thought about replacing the wires too - and still may - but checked these plugs out first. So glad I did - the improvement was instant and very noticeable. Revs faster and smoother. Me likee!

    There are two different types of Screamin Eagle spark plugs that are listed on the HD site to fit a 2016 DWG. One is part #31600105 and the other is 31600106. I cannot tell by the descriptions what the difference is. Can HD clear up this mystery?
