    So far so good! Paired with iridium plugs on my 2006 RK,they seem to be a major improvement over the OEM plug wires. Installation is possible with the fuel tank loosened, however, the original double clip is too small for 10mm wires.

    spark plug
    I don't know why these people can't put the length in inches on the spark plug wire so we know how long they are

    • Try a tape measure? That would tell you how long they are. Post what they are as I'm looking to see if they would fit.

    I put these and a set of Screaming Eagle plugs in my 15 Street Glide. It was a major improvement to throttle response and idle. I would recommend.

    What's the difference between the 31946-99C and the 31939-99C plug wires. They look identical with the same color red and are the same price. Both will fit my 2003 Road King.

    • Answer:
      Hi Rufus: Part # 31946-99C are orange and Part # 31939-CC are red. That seemss to be the only difference. Thanks princessv
