    I use it on the wires at both ends, distributor and plugs.
    Also, use anti-seize on the plug threads. The silver type works fine.
    That is a MUST on aluminum heads, but is also good on iron heads.

    Makes it a ton easier to remove the wires later.

    I use it each time I change plugs or wires. I buy it by the can with a special nozzle that fits down into the plug wire ends. It keeps the wire from sticking to the plugs, lowers the possibilty of moisture build up, and helps conductivity.

    We have people come in all the time wanting one plug wire because they broke it taking the wire off the plug. They did not use the grease. I recommend it with all sales of plugs and wires at work. It is also used for reducing sqeaking in brakes, holds down corrosion on battery posts, and should be put on all light bulb connections for the same reasons.

    Great stuff!

    We use it depending on application. Di-electric grease is a great insulator. It seals up the wires and helps keep good contact. We have issues with it on some engines with plug tubes. The HEMI for instance gets so hot in the plug tubes the grease burns to a thick brown film that damages the coil ends. We have been told not to use it on the spark plug tube type engines. I go through a jar every few weeks at work. I use it on a lot of connectors. Just dont put it on an O2 connector. They need to bring in fresh O2 through the wiring and it will fail. Lots of guys get burned on that one.

    This is something I've wondered about. Isn't dielectric grease a CONDUCTOR, not an insulator? So, when you put in a spark plug boot, aren't you putting a conductor between the top of the plug (connector) and the grouded spark plug body? I know people use it but I don't understand why its not a problem. Can someone explain it?
