Spark plugs coverd in brown-ness-ness

[adamdaddum]

Hi, ive just inspected my spark plugs but I am unsure as to what im looking at!
Is this just a worn spark plug? I think you can tell if an engine is burning oil/lean from the plugs but I cannot remember whats what.

If anyone could advise it would be much appreciated!

Thanks in advance Adam

why do you have bosch super4's and not the correct NGK plugs?

They are just the plugs that came with the car, I know the F4R can be a little fussy so I will make sure I put the correct ones in when I service it (sometime soon!)

Oh and thanks JackJack..

Normal Condition
An engine's condition can be judged by the appearance of the spark plug's firing end. If the firing end of a spark plug is brown or light gray, the condition can be judged to be good and the spark plug is functioning optimally.

Looks like its healthy! Yay!

that looks like it's come out of a healthy engine.

They also look like Bosch super4 plugs, in which case, file under B1N, and get some NGK's

Want me to add some NGK's to the list for Wednesday Adam?
