some applications need no dielectric grease. Power steering kits on the commanders have to be dry connections, not sure about the xms, but if getting to all the connections is anything like changing a spark plug.....i'll take a pass on it.
Well was just adding some to the connections yesturday as I have the sled apart. The connector for the rave valves was already seeing corrosion after 1 season and 1 of the spark plug wires had a massive build up of black arching dust.
