To find an appropriate Bosch oil filter for my 2014 BMW 320d F31, I shopped around at two separate retailers.
I was wondering if anyone knows which one is right or if both of them were correct; one said P7123 and the other said P7205.
I am grateful.

This is where I discovered the Bosch part number P7123; I used it.

The next thing I did was search for an authentic component, and I found one

P7123 corresponds to n47 and P7205 to b47.

Apologies if this is a really inane question, but how can I visually distinguish between an N47 and a B47 chassis?
Much obliged

You can find out what engine your car has by going to the realoem page I linked to. If your car is pre-LCI, it will be a B47. If it isn't, it will be an N47. Alternatively, you can enter the last seven digits of your vin in the special box and it will tell you.
