Bosch Oxygen Sensors New Part Numbers

[Turbo_ZA]

This is from Bosch's 2009 Oxygen Sensor Catalogue. It quotes OEM part number in one column with the appropriate universal unit next to it.
The part numbers have changed - no idea how long it will take for the new numbers to filter down to auto part store levels.

Last time I replaced my O2 sensor, in July 2008, I purchased a Bosch #13942 oxygen sensor from NAPA for $43.99 + tax, and spliced the wires into my 968's connector, using solder and heat-shrink tubing. I kept the wires exactly the same length as the OEM so as to avoid significant changes to the overall electrical resistance.

The O2 sensor #13942 is for a 1987-1988 Ford Mustang V8. The sensor itself is identical to the Bosch #13011 that NAPA sells for $139.00 + tax; this speaks volumes about what we pay for Porsche's proprietary connectors!

You must be fortunate to have the O2 sensor working after you used solder and heat-shrink tubing. I have never seen anyone advising using solder.

O2 sensors are to be crimped only.

From FR Wilk== http://www.the944.com/
Do Not Solder Wires!
Use wire crimps or Posi-LockÒ. All the latest BOSCH O2 sensors are air tight. But the O2 sensor must have a clean air supply to work. It breaths down the center of the multi-stranded wire(s). Solder and solder flux will close the air-gaps between the strands of wire and the O2 sensor may malfunction.

Well, I did, and would advise anyone to do the same. It's a secure connection in a high-temp environment. Electric current didn't seem to mind.

People have said that a Ford Taurus oxygen sensor works in our cars, but dont know the model. I think 924board has a page where they have alternative part #'s for our cars.
