Changing out O2 sensor as part of routine maintenance. Anyone have experience with the use of a universal type replacement sensor in which the wires are cut and the original connector wires are crimped and heat shrinked to the new sensor. Used this type on my old 1983 SC without a problem. Just wondering if the 964 is a little fussy and an exact replacement should be used.

Hi,
I've seen posts (quite recently) that said you should not use the universal ones - the OE ones are waterproof and the universal ones are not.

Does anyone have the Porsche PN for the O2 sensor so I can shop it around. Thanks for the advice.

The PetCD has 964.606.124.01 listed as dropped, use 965.606.126.01 as a replacement. If you call one of the major discounter porsche dealerships here in the US they'll get you the correct part and probably cheaper than aftermarket.
