MSD's Spark Guard is a dielectric grease that solves many common ignition troubles. It 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 MSD Universal Spark Plug Wire Sets. Spark Guard will not dry up or harden so it will retain its spark isolating capabilities indefinitely.
