All 8 contacts are identical regarding the burn/witness marks. Plug wire resistance is within spec. Plugs were 30k old. Standard Bosch WR9DC. No platinum or other odd ball stuff. Am I using the wrong sparkplug? Bosch website calls for a 7511 in Super which is a W9DC.
Is that (R)esistor difference causing a problem? WR9DC vs W9DC
What is a good source for conductive grease? It's worth a try.
