Replaced as part of troubleshooting a strange vibration after valve cover and upper timing case cover gasket replacement job. Thought they might of gotten damaged somehow. I was taking shots in the dark and replaced plugs, coils and vanos trying to find a solution. Turned out to be something totally unrelated. Decided just to keep them anyways.

I'm at 79k miles. Went with some knocks offs from Amazon. 1 of the 4 I got was a dud (threw misfire codes on that entire bank). But exchanges are always easy with Amazon so not the end of the world. Replacement one was fine.
