when installing spark plugs, do you use a special lubricant/grease? ive seen at oriellys a small packet of spark plug lubricant? and i think ive heard other car mechanics say to add a tiny amount? maybe scotty can make a video of "what" and how much and where to add this, if it is a thing i would like to know? can i get help?
Scotty's explanation
I always use NGK Iridium spark plugs that already come with threats coated from the factory. Do not use anything on NGK's. Not familiar with other spark plugs but you should read manufacturer's installation instructions. Below is NGK install info:

Risk of incorrect torque
I am under the understanding that spark plugs are made with a special metal that doesn’t corrode, so it is not necessary to use lube.
But I am open to learning differences of opinion from more knowledgable folks.
Not a straightforward question to answer. Take a look in the archives for a range of opinions and check the manufacturer’s website for the final answer.
