Not only was my RX8 coil discolored on the bottom.

IT WAS DEAD!!!!!!!!!!!!!!!!!!!!!!!!!

I could have lost the engine any minute.
No indication what so ever that it was dead.
No noticeable loss of power. Of course that
was the trailing (top) plug.

If the check engine light had come on I would have known
about it but it did not!!!!!

Minutes away from a new engine!!!!!!!!!!!!!!!!!

Check those coils folks. I'll do it for you including
shipping for $20 cash. All four. For a limited time
only. Better yet get four new ones.
Mine should be in in a day or so.
