MSD Spark Guard

Product images may differ from actual product appearance.

MSD's Spark Guard is a dielectric grease that solves many common ignition troubles. MSD Spark Guard stops voltage leaks, eases boot removal, prevents moisture buildup inside the spark plug wire boots, and even helps protect against radio noise (EMI). It also simplifies the installation of new spark plug wire sets by easing the boot over the wire. Will not dry up or harden so it will retain its spark isolation capabilities indefinitely.
