Used nos octane boost has mmt in it. I believe that's the reason for the Orange color.

looks ok to me, yes the octane booster will color them orange but I still see some tell tale signs, such as the ground strap is 2 distinct differnt colors changing in the bend. I also can see the center core elctrode is slight silver on edge with a darker center so youd have a bit of temp drop safety in there yet. The one plug in the pic looks blacker but is not in focus to see. When you do a plug check you should take the sled out to afield or whatever and run it wide open for a good 750ft long at least and then just shut off the kill switch and coast to a stop, pull the plugs and check them to get valid information, as once you slow down, or idle it ruins the readings.
Yeah one appears to be less orange. Upon close inspection center core has small silver edge going half way around the strap half. I will try and do a full throttle check next time out thanks don.
