Plug Condition

[Hootie]

Replaced plugs on recently purchased 2013 GTS. Anybody that can 'read' these? Didn't quite match up to diagrams I found online. 24k miles (or 6k if they replace with engine replacement). Just swapping things out to start fresh. Also did the belt, wires, air filter, oil. Next up is diff and trans.



Any comments? Good plugs? Normal looking? Engine about to explode? Thanks!

They look normal-ish to me.

How do you drive the car? Do you have an oil catch can in place by any chance? Looks like a fair amount of carbon build-up, but I can't tell you if that's normal for your engine or not. What do the other 9 look like? If they all look about the same, that's probably a good sign that your engine is doing fine.

[Hootie]

They all look more or less the same. No catch can. 90% of the miles I put on the car were driving it 9hrs home, all highway cruising. Other than that it's a street car, no track, just some pulls on open roads once it's all nice and warm.
I have no idea what 'normal' for this particular car is as it's new to me.
Bone stock. Thanks for the feedback. Just wanted to get someone who has seen plugs out of these motors before to let me know if I should be concerned with anything.

From that pic, nothing looks unusual

Thanks for the feedback. I'm no mechanic so learning as I go. I appreciate the opinions. Glad nothing looks alarming.

Some interesting spark plug pics in this thread if you haven't already seen it, including a pic of one of my plugs from my Gen 4 (uses same plugs) pulled at around 4,600 miles of use:

Except he doesn't appear to have a thumb.

Came to post this, leaving satisfied.

Steve gave us some laughs in there for sure.
