MSD Spark Guard Dielectric Grease
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). Spark Guard will not dry up or harden so it will retain its spark isolating capabilities indefinitely.
