    The Bosch part number should be shown on your existing WURs -- 0 438 140 XXX (please post what "XXX" is if you can).

    Larry Fletcher at CIS FlowTech:
    https://www.cisflowtech.com
    (send a text to his phone number, not an email)

    or

    Fuel Injection Corp:
    https://fuelinjectioncorp.com/r-r-program

    could probably rebuild your existing WURs (or they might be good sources for information, too).

    That's more typically known as the "Auxiliary Air Valve" or "AAV". I'm very sure that Bosch 0280140176 is not the correct AAV for a early euro K-Jet TR (so yours must have been replaced previously), but there seems to be a lot of substituting/superceding in the AAV history so you might get that one from a F part supplier if you ordered a "new" one today. Here's what I think I know ;):

    Bosch 0280140176 = Ferrari 146557 = used on very late euro CAT version TR with KE-Jet. Has an unusual "V" shape to the closing disc aperture rather than an "arc" shape like most other AAV:
    (please forgive the terrible focus)

    Bosch 0280140104 = Ferrari 113974 and Ferrari 125880 = used on US version TR with KE-Jet and many other F models.

    Bosch ? = Ferrari 124802 = used on early euro version TR with K-Jet. The picture of this AAV at Maranello Concessionaires shows Bosch 0280140173, but the "high" ...173 part number must be a later substitution. If someone has an early euro version TR with known original AAVs, please post the Bosch 10-digit part number.

    IMO (if we can't get a more correct Bosch PN for an early euro version TR AAV), you'd be OK using something like 0280140104 or a similar one from a Fiat/Volvo/Alfa/Porsche/etc. like romano suggested. Any of those couldn't be any more "wrong" than 0280140176 IMO.

    Thank you Steve.
    Great information as always!
    I located and ordered two of 0280140104.
    I'll report back once they're installed as to if this is a good substitute part number.
