Hello All, I am posting this short note because this has been happening far too often in regards to spark plug installation. People are asking for diagnosing misfires related to spark plugs and after numerous posts, it turns out that they are not using dielectric grease when they install their plugs.

Please apply a thin layer of dielectric grease all around the ceramic part of your plugs before installing them. They prevent arcing and misfires. This is recommended on stock coils and plugs, so you KNOW it is mandatory on BimmerLife and PR Coils. If you don't do this, you most likely will develop misfires and potentially damage your coils and plugs due to the electrical arc pathway.

Clean the metal tips and coil collars before installing to be sure there is no film interfering with the coil innards and the plug metal tip. When you remove the coils next time, it will come out much easier so that is a plus.

Cheers.
