In simpler words, dielectric grease helps extend the life of your spark plugs, it is important to have one with you. The only thing to remember is that you shouldn’t use it on silicone-based plastics and rubbers. Since both of them are silicone-based, the effect can be negative. Also, keep the grease away from mating surfaces such as sockets because it is a bad conductor of electricity.

How to use Dielectric Grease on Spark Plugs

It’s quite easy to apply dielectric grease but you must be careful nevertheless. Take a little of it and apply it to the rubber boot. After this, spread it gently so that it covers the area. That’s about it.
