Some of them seem quite dirty (at least on the threads).
Did you by any chance keep track of which is which (cylinder number)? The electrode on some does seem a bit short but that might be normal, you'd neet to compare with a new one. |

Yes, they go 6 -1 left to right in the pic. The clean one was wiped. It may be that I used to much anti seize when I put them in. I don't recall the electrode sticking out. I'll check the parts. Thanks. But is the light brown/whitish normal?

Found these on Amazon. NGK's. Notice even the BMW OEM the electrode doesn't extrude beyond the ceramic casing. I wonder if I am running lean and hot. Even though I have never over heated.

On the pictures, yours seem to be recessed but that may be perspective.
as for the color, mine were the same, I'm not expert enough on modern engines (give me an old aircooled and its an other story) but brown usually is good. Knowing if you're running lean or rich need looking at the fuel trims with an OBDII since the ECU will adapt the mixture to run correctly. Do you have an issue you're trying to pinpoint or are you worrying because of mileage? |

The color looks perfect to me. No oil residue and if you were lean you would experience knock and the plugs would look like peppered.

Ok, than I guess I can proceed with the intake manifold / ccv, vacuum line updates going forward. I was concerned because I have high mileage.I think I was concerned about coolant leaking into a cylinder or two. But I have been very good about maintaining the vehicle. Thanks.

WOW, that's what I am talking about. I think I should replace those block water hoses , they're original. Did you have any issues with abs/speed sensors? Are yours original?
