Over the weekend, I installed a set of Magnecor "CV" spark plug wires in my F-150 truck( V-6). I found that the wires do eliminate the ignition noise that I could not get rid of previously.
Downside was the cost: $ 128.00 for 6 wires is steep, but it did work.
My rig mobile is an Icom 706 mk2, and Hustler mobile antenna
Thought I'd pass along my comments, as a number of Hams have asked about these wires.
Good Luck to all.
