pre and post cat sensors same in 986?

[ericinboca]

I did a search and found a post that says the pre and post cat sensors on the 996 are the same.

On an 04 986S, does anyone know if the pre and post cat sensors are the same, other than the post cat sensors having a longer wire?

I do not know for US, but you can find that info in the PET.

They're the same - I replaced all four of mine (03 986S) with Bosch 15738 sensors. 04 should be the same

No they aren't the same

if you buy Porsche or Bosch parts (Bosch makes the Porsche part). The pigtails for the sensor in front of the cats and behind the cats have differing pigtail lengths. The actual sensor is the same part. Part #s differ by model year and engine.

If you buy generic sensors and wire them yourself (no soldering) then the parts can be the same.

Some part #s here
