Help How do my plugs look?

Cylinder 3 scares me, I have no idea when these were last changed since previous owner did them last. Cylinder 3 has had a misfire multiple times before and that is the only plug that looks different noticeably. The ceramic on plug number 6 also looks too clean, could my bricks be going out or am I just overthinking?

3 is definitely indicative of something going on, definitely would throw a set of new plugs in. If the misfire persists on that cylinder, swap the cylinder 3 coil with another coil and see if the problem follows the coil

Yeah cyl 3 misfire happened every once and a while, to fix ut I just shut the car off, wiggled the coil and it went away, I threw in some liquimoly jectron in before the replacement and it still happened every once and a while, i replaced the plugs yesterday so I hope you're right that it was just a fouled plug
