Are these suitable to replace my 2 x POST CAT lamba sensors?

The description says
Exhaust System In front of catalyst, Length(mm) 950, Part Spec 5 wire

So I wanted to check as my pre-cat sensors are OK.
 
Phil, that ecp part is definitely pre cat, both from the description and also the 950mm length (this is the correct length for pre-cat).
You want post cat... BMW part #s
11 78 7837564 x1
11 78 7837565 x1
Afraid I don't know the Bosch code for them, but I'm sure with a little digging you can find that.
 
Thanks Tom, I was afraid they would be different front and back, glad I checked!
I know the OEM prices are about 210 each so I will have a hunt for the Bosch equivalent.
 
I sent those back from lamdasensor as I wasn't happy with the bosch stamp having been etched off. The chap tried to convince me they were real and would have been fine and I suspect they would have been, but member on here andy beech after much digging (thanks andy again :thumbsup: ) found a source from germany that did the correct genuine bosch sensor however the cable was 50mm longer, hence the different part #. It was impossible to get the exact correct BMW spec part for some reason. Anyway, I digress! try here

I only did the pre-cat ones.
