today i had the time to take out my couple of my spark plugs to look at them because my car lately have been acting up and just wanted to take a look and what i saw scared me so much and now i dont feel safe to drive my car. the spark plugs are very black and look kinda oily on the side. ill post pictures so you guys can see
only mods on the car is CAI K&N and predator turner and its my daily driver and i have the 91 CAI tune in it.
is it the tune thats messing up my car? or what do you guys think any input will be good.
my car is a 2007 Chrysler 300c with the 5.7 hemi
mods: CAI. diablo predator. running 91 CAI tune and daily driven .
Do you have the right plugs in there? Are they all the same condition? It looks like they're the wrong heat range.

That's the correct spark plug number....................
Looks like that cylinder is running way too rich or is burning oil.
Might be bad valve stem seal, broken piston ring, or who knows??????????
Time to take it to a qualified shop and stop guessing what the problem is..................
Have them do a cylinder leak down test, that might tell you what the problem is.
Florida rt- its not oil cuz it would be all aaround I think it's like carbo build up
i took apart all the sparks plugs all like about the same color I'll post a pic later but the black stuff comes off the plug like if u peel it or use ur nail to sketch it yesterday I put a bottle of lucas see if it helps clean them up and also I put the car back to stock tune
Maybe try some SeaFoam?????????????
Just one plug is doing this? Sorry, I'm a bit slow.
If the leakdown test doesnt show anything, try swapping injectors.
Oh and by the way, you're not in the hurt zone for your motor just yet.
the other plugs are like this
i put a full tank and i put a lucas deep cleaner and i put the car back to stock tune and ive been driving it it feels ok
are the two dark plugs on the same coil pack.....
I would run a compression test.....
