Are these only obtainable via a main dealer .. or is there a less expensive option?
Have you taken them to a local parts house and let them cross reference them. See if they can match it physically instead of saying that it is for a Ferrari.
Peter -- Are there any manf/PN markings on the body of the O2 sensor (e.g., Bosch and a 10-digit Bosch PN)?
Hi,The sensor wont be the problem,the connector may be or maybe not,im sure this is not a dealer component,it will cross refrance into somthing else,
good parts chap will help you here,
you do not have to buy them from the dealer, look on the internet under Bosch oxygen sensors to find the correct numbers for the sensors, there are two numbers, one for the sensor b4 the cat and another for the sensor after the cat. the other option you hav is to buy the sensor with the ferrari connector already on, or you can get the universal type sensor which you will have to splice to the existing connector. there is an approx. saving of 50 per sensor if you go with the universal sensor. most part stores carry Bosch sensors. I purchased mine from Auto Zone.
let me know if you need the Bosch numbers as I just purchased 4 for my 1997 355.
These things are generic 2 wire and 3 wire (heated) devices. The generic versions are cheaper than Bosch and come with pig tails....you'll have to splice on your connectors from the old ones....need a soldered, and high-temp insulated splice. The cheapest I've found were about $45 each.
Rocky ... I'd sure appreciate those numbers ... how much for the 4? Mines a '96 355.
the bosch part numbers are;
15738 after cat., universal type
13820 after cat., oe type
15727 b4 cat., universal type
13309 b4 cat., oe type
the oe type cost me approx. 130 each
the universal type cost approx. 60 to 70 each
i went with the oe type as they were out of the universal types.(oe types have new connectors so you don't have to splice the sensors to your old connectors)
Can you post the numbers for the 95 F355 also both oxygen sensor and thermocouple.
Forgot to mention ... the thermocouple also needs replacing.
Is this a BOSCH part also?
Regards & thanks for the tips.
thermocouple is not bosch....unfortunatly.
are you sure the thermocouple is bad? if you are getting a slow down light the problem could be the cat ecu (this cost approx 225 dollars. the thermocouple plugs into this ecu, there are two of them. the new, improved ecu uses a green semi potting material as compared to the original potting which is black and hard.
I've got the green ones now too.. they look rock solid - I doubt any moisture can get in these babies. the old ones had a gap between the side and back covers.
No slow down light .. but took it to the main dealer and they said an O2 sensor was out and also 1 thermocouple. Apparently the latter (old ones) were prone to cracking and then a bit of moisture would wreck the thing.
