Hi Guys, I'm looking to replace my plug wires at 75K because of rough running at hot and the fact the wires appear to be "glowing" during a "water Mist" test. Questions: Can you apply tubing over the wires to make them last longer or is this not a good idea? Has any one tried the Non-OEM wires from Beamer bone yard? They are about $150 cheaper than OEM. I really don't want to spend $250 - $300 for plug wires.
