You should only grease the inside of the boots, and maybe put some on the porcelain plug shell. Try to keep it off the actual contacts and definitely don't put it on the plug tips.
Dielectric application:
1. Grease the plugs ceramic before install. This assures proper seat. Without it, the COP boot may buckle.
2. Pull the boot, then give the spring a couple tugs to make sure the spring to coil blade connection is secure.
3. Grease the entire inside of boot to protect against moisture and to focus coil pulse to the spark plug. Without it, pulse jumps, etches and leaves carbon trails inside of boots. Boots become weak and can deform.
4. Install the boot over the spring and onto the coil. With a small screw driver or curved pic, pull the spring from the end of the boot approximately one half inch. Slide the screw driver across the spring, keeping it from recoiling back into the boot.
5. Clean grease from spring end with a grease cutting agent. Lacquer thinner or brake cleaner works best.
6. Release spring so that it recoils back into the spark plug boot.
7. With a small brush or finger, grease the top seam of the boot.
8. Install coil.
You can further protect using clear GE Silicone between the boot and cylinder head. That's more less an option, but it does work. ____
