The dielectric grease is to prevent moisture from getting into the electrical connections to help prevent corrosion. Put a blob of grease on the end of the spark plugs (NOT the end that goes into the engine), or into the ends of the boots on the plug wires before you plug them on, and onto the mating faces of the electrical connectors that plug into the coil packs. Probably want to spray the connectors with Electronic Cleaner before applying the grease, too.
