I have been running the live wires and screamin demon coil in my 08 JKU for around a year and a half now and haven’t had any issues. The wires can definitely take some heat because I noticed that my #3 wire (from what I remember) was practically sitting on the manifold one day but it didn’t show any signs of damage and is still running strong. I have my plugs gapped to .060. One thing is that even though the advertising states that it doesn’t cause radio interference, I still get a little whine, that will increase in pitch when I rev the engine, every now and than that I can hear when I’m running an MP3 off of my factory stereo and there isn’t anything playing but the volume is turned up, nothing that is noticeable with anything playing though.
