What do my plugs tell me? My car was detonating something fierce after my tune. So i thought id start with the plugs and see how they looked. I pulled all 8 tr5's gapped at .38 and replaced them with the factory a/c delcos gapped at .50's. Anyways, heres what all 8 plugs looked like when I pulled them.

You're looking at a plug that's been fowled by Methylcyclopentadienyl Manganese Tricarbonyl (MMT).
MMT is used frequently in Octane Boost, especially in the brand "104+ Octane Boost" and "Super104+ Octane Boost".
you can clean them off, and it shouldn't affect the plugs performance

It seems to be running great since i changed the plugs out. We'll see how the next few thousand miles go.

Yeah, I put a bottle of lucas octane booster in it a few weeks ago before I went to the track, It was a useless attempt to combat the horrible oklahoma 91 octane.
