I still haven't bought the replacement yet, mainly because I'm unsure of the part number, it could be any one of the 4 which are pre-cat. So, I asked AI to identify it, and this is what it came back with. Does anyone agree or disagree?
- Based on the information available for the W12 engine, Bank 3 typically corresponds to cylinders 7, 9, and 11.
Therefore, the part number you need is: 07P906265H (Cylinder 7,9,11) (Grey) In front of catalyst
The plug has a length of wire attached, so it won't be as simple as say, a spark plug, where I could just pull the top connector away as the wire comes as part of the assembly. Is there a way to find out where it goes and what it plugs in to?
