The early 2013 cars had a bad tune which caused detonation and was also causing the injector seals to go bad. This was fixed with a new tune which can be applied to any 2013.

^that's what I meant. I do not have rod knock but do have detonation at times but only under hard conditions. I monitor it and usually mixing in some 100 Oct fixes the problem (I'm in CA so this gets me to 93 Oct vs. the crappy 91 I got)

Lastly, I seem to hear a very faint knocking noise from the engine but it's only just started happening on these cold mornings. I haven't noticed it at all when the car is warmed up. It is very quiet. I've also noticed a little oil consumption, about half quart in about 5K miles. Car runs beautifully. Any ideas? You say your car knocks, isn't that really bad, like the motor is going out?

I don't know about the coil packs. I haven't loss one yet but now that I am tracking I am tossing it in with the wear items. Heat kills them from what I have seen.
I don't really have a ton of oil issues. My timing cover has been leaking for a while, but not bad enough to get it fixed. And the blowby is enough to measure in the catch can but not enough to see a loss between changes (I usually change my oil between 5k and 10k depending on what kind of driving I've been doing)
I do know a few other local owners who experience faint rod knock on cold start and they are around 60-70k miles on the car. Not sure how fast it is progressing for them though. Both of them track occasionally as well, like 3-4 times a year.
