I had a dyno tune a couple days ago and the dyno operator said the Accel plug wires I put on are junk and only use OEM plug wires. I replaced my OEM wires a couple months ago because they were 2004 original and hard as a rock. I put on Accel 8.8mm spark plug wires and he had a lot of trouble with the dyno reading RPM off of the plug wire saying it was bad plug wires. Ever price OEM plug wires? The most expensive foot of plug wire out there.
