To lubricate a spark plug boot, first, ensure the engine is off and cool. Remove the boot from the spark plug. Use a small amount of silicone-based dielectric grease and apply it inside the boot and around the spark plug’s ceramic insulator. This helps with easier installation, removal, and prevents voltage leakage. Reattach the boot onto the spark plug securely. Regular maintenance can prevent misfires and ensure smooth engine performance.
