That is exactly the point of dielectric grease ... it is non-conductive. It keeps moisture out of your electrical connections without creating a path to ground or bridging two contacts. Also makes it easier to remove boots from spark plugs. I use dielectric grease on every electrical connection I take a part, including the boots at both ends of the spark plug wires.

The grease does not interfere with the contact between the plug and the wire since that is a hard contact. It keeps moisture out of the connection. I'm sorry that makes no sense to you, but if you don't trust our expertise please feel free to do whatever you want. We provide advice based on our collective experience. It is your choice to follow it or not.

Basically, the grease gets shoved out of the way when metal contacts with metal. So, instead of there being air in the gaps, the whole connection is encased in goo. This prevents moisture from getting in, and corroding the connection. Over time, the corrosion gives you trouble getting it back apart, and can cause issues with the connection as well.

I had to get under the car to get at one of them...I did use the di electric on the tips of the coil packs and plugs and a smear on the porclin...
seems to run good now and the place I bought them is replacing the bad one at no charge...
Thx for the help

The dielelectric grease is awesome to use, but to much is a bad thing as it doesn't allow the plug boot to properly mount the spark plug post.
Another item to consider when replacing the plugs is to put a light coat of anti-seize on the spark plug threads.

Yes, use the grease sparingly. Just a light coat is fine.
Please tell me you replaced all the wires and not just the back side?

Oh ok. Yea the new ones should be long enough to where you can drape them right over the top of the intake plenum. I've seen some plenums with built in wire holders too.
