Good Maintenance Practices:

Before purchasing and installing a spark plug wire, make sure they are the correct size and fit for your vehicle.
Remove the wire by holding the boot, not the wire.
Keep plug wires free from contact with other engine components.
Reinstall plug wires in the original position, using correct routing and utilizing appropriate hold downs.
Regularly inspect your spark plug wires for signs of damage or wear, and replace them if signs of damage are found.
