Picture of my spark plugs and question So took my plugs out bc i'm doing headers and true duals... and i'm buying the msg/ngk plugs kit for a fresher setup. Do these plugs look ok? I don't really know much about how they should look when the car is healthy but it looks like one side has more scum on it then the other. Any help to a spark plug noob would be appreciated.

How many miles on the car? Whats all done to it mods details? Hows the car run now? To me those plugs look like theres alot of carbon on the electrode possibly oil burning valve guides/blow by and or rich.... however with old plugs its not really accurate to read them.. the correct way would be fresh plugs and make a 1/4 pass shut it down at wot and then pull them and take a look. A good plug will read coffee brown on the porcelain.

Also taking a second look u could be running lean by the color of the porcelain. Someone else might jump in with there thoughts as well. But like I said earlyer a fresh set is the proper way to get a good read on how your running.

The tip of the plug is all you really need to worry about, and they all look similar.
The yellow discoloration on some of the plugs in no way hinders the performance of the plug.

So they seem to look pretty good at the tips as well I did notice that, there not covered in oil like I have seen some look nasty.
