  • Use At Every Plug Change
  • Prevents Plug Boot Sticking
Dynatex Spark Plug Boot Seal should always be used inside spark plug boots and distributor boots to eliminate spark leaks common to HEI and hi-performance ignition systems. Applied in a thin coat, the seal acts as a voltage insulating gel by filling air gaps. The seal also prevents rubber deterioration and stops plug boot sticking. Did you know? Many people in our hobby refer to spark plug boot seal as dielectric grease.
