    Wires did not fit my STOCK coil and the lettering came off by just rubbing on it. Front cylinder about 1in short. Junk

    Does not fit

    The long wire is 1"3/4 shorter than factory so it cannot be run properly. Called Harley Davidson and they could not even give me the dimensions of their own product! This is ridiculous considering how much everything from Harley Davidson costs! Never again, aftermarket all the way now.
    Wasted my time
