Hello everyone. I just changed the spark plugs on my 2018 IS350 F-Sport (which took forever lmao) and I was wondering if there is anything I should be concerned about with the old sparks. I have had the car since 2022 and about 43k miles and have no record if they have ever been changed. Lmk what you guys think! I don’t burn any oil and do oil changes in 3k intervals.

Here mines at 69k miles

they look just fine.

I assume you're using synthetic oil. Why are you changing oil at 3,000 miles?

I don't see anything I'd be too worried about. Number 5 could be slightly lean, but again, it doesn't look bad. I would also keep an eye on #2 and #5 spark plug wells for signs of oil seepage in the future.
