In foggy weather I get arcing at the top front coil wire boot (#6) to the coil pack housing. That's about 1/4 inch. The arc does not go thru the boot; the arc is from the non-wire end of the boot, and it hugs the surface of the coil pack's potting compound. Coil pack was replaced long ago. '95 VR6.
Would packing the boot with dialectic grease potentially solve this?
Would getting new plug wires as a way to get a new boot be the normal solution, and is it usually successful?
Other?
