    These wires hold in place very snug. Paired with new spark plugs, bike started up effortlessly. 10/10 would recommend.

    Do u sell the wire loom or the zip tie plugs to secure the wire away from the motor or from falling down onto the horn?
    Jwdragon54 - lincoln ne
    • Answer:
      Jwdragon54, We do sell zip ties with frings on them to be inserted into holes. You did not mention a model or year and if there is a hole near for the christmas tree ziptie to be inserted into. Zip tie christmas tree part number 10177. Thanks, LeakyShovel73

      • Answer:
        Hello Lucien, Yes, depending on the year and model. Nearly all Dyna models secured the plug wires by PN #10214 retention kit & PN #10177 cable straps to retain them to the upper engine mount bracket. Your local dealer can also help if you’ve made any changes to your bike for possible solutions. Thanks, shvlhd read more.

    Are these compatible with the Delphi Ion-Sensing coils? As in, will the knock detection capabilities still function normally?
    Moody - AR
    • Answer:
      Hello Moody, We have not tested these wires on after market coils so I couldn't answer on if it will work for sure. But through experience a spark is a spark, my guess is the function would still be there. Hope this helps. Thank you, wildonemke
