Spark Plug Wires

Recommended Posts

2003 HD 1500 6 L, having difficulty removing the spark plug wires from the spark plug. What is the trick, I pulled hard on both the aluminum cap surround the plug boot and the plug boot and was not able to get the plug wire off the plug. Is there a special tool that I need to remove the plug wires?


Thank you for the help.

Twist and pull.


Use a little bit of silicone or dielectric grease on the inside of the boots when reinstalling (not to mention anti-seize on the plugs).
