Conaero can you kindly help me out with bosch generic P/N for both upper and lower sensors as they are different size and OEM P/N. I also note that the connectors are different. Many thanks in advance.
I’ve asked MAF he has a guy who makes them up. Just get your old ones out ready to send and he will take the plugs off yours and fit them to the new ones.

There are basically 2 types a 3 and a 4 wire wideband. The rest is just cable length and connectors.

What engine no is your car? If it does have 4 Lambda then it likely that it will use 0258 003819 for the front and 0258003820 at the rear both Bosch the rears have longer link cables. You need to check the above with Bosch the fronts I know are OK because l have had them on my 3200 for 8 years l am guessing the rears are a match because Ferrari used used the same fronts on the 550 and then uses the rear part numbers l have given. Bosch also do universal sensors LS07 and LS05 but you then have to cut the leads to length and put the connectors on at the bulkhead end.

Wonder why they did that with 4 sensors.. as far as I know all early 3200's were Euro 2 spec while the later 01 cars with the air pump system scraped into Euro 3

My order, which should be here next week or so, is for 4 Bosch 0258003819 sensors. I only need 2, so the others are spares. The second pair of 'sensors' are thermocouples, I gather...
Greg, my car is one of the last 250 cars made hence requiring 2 sensors per bank. I now have the info to try and source these locally..........I recall using Repco to replace a lower sensor some time ago. Cheers

Chaps, I have sourced the 2 required sensors for Bank 2.........Bosch LS07 and LS05. Has anyone had experience with the connector plug provided with these universal kits, there doesn't appear to be anything stopping the wires from separating and open circuiting after plug assembled! It looks like the rubber plugs are squashed tight around wires when plug pushed together stopping wires separating but solder feels much safer. I would feel better soldering the 4 wires and using heat shrink to protect has anyone done this and not used joiner plug? Given them awkward nature of this job I want to get it spot on. Thanks in advance.

Ok................universal Bosch LS07 (upper) & LS05 (lwr) Co2 sensors replaced on bank 2. Ended up using supplied joiner plug rather than soldering no CEL at start up need to take for decent test drive to make sure all good. Removing exhaust to get at upper sensors a real pig of a job some of the turbo flange bolts are a real treat to reach!
