Fortunately a fairly quick fix, decided to just use up the ATE Blue.  Since the M Coupe is going to be destined for street weekend warrior use, rather than more track days, decided not to upgrade to the Motul I had on hand.  I also fixed the loose O2 sensors after removing the center silencer (resonator.)  While I was in there I noticed a little chaffing on the wires, so I added some high-temp silicone tape.
