1 Top Rated Question

How are these wire protectors installed? Do they simply slide over the wire and plug or do you have to remove the wire boot to get them on?

  • The Heatshield Insul-Boot Spark Plug Heat Shields are designed to slide over your existing spark plug boots. Removal of the spark plug boot is not required.

    Good Quality

    Great quality product however they do not fit over the boots for the livewire plug wires but they are excellent with other plug wires.
