Finally replaced all 4 O2 sensors w/ generics for $160.

You need to post pics on which wires to which wires or do a detailed write up. This could save everyone 300 bucks or so.

I did use the heat shrink and took pics that I can post once I get them off the camera. I will try to post it on my website too asap, but really busy right now with work and other obligations.

For the wiring, it's very easy since the universal sensor has the same wiring colors as the old sensor. I just wired black to black, gray to gray and the two whites to the two whites. The two white wires are interchangable so it doesn't matter which way you wire those two. I also used some of the plastic wire shielding to protect the connectors from the heat. It's the tubing that looks corrogated with a slit down the side that is used to bundle wires together.

Btw, you can't search for the Porsche Boxster O2 sensor and find it. The part number is USOS-4000 and you will usually find it listed under Lexus and Audi vehicles. I found them Speedy Auto Parts for $34.64 each so it's even better.

Nice, I dont need anymore info. Thats all I need, thanks. If they are working well Im doing it myself. Actually is there a difference between pre-cat and post cat 02 sensors?

Nope. The only difference in the original ones is the connector plug on the end of the sensor. If you look up the Bosch universal sensor for Boxsters (about $100 ea) the same part number is for pre and post cats. In fact, any 4-wire sensor that physically matches the screw threads should work fine.

Parts Train doesn't seem to come up with any way to select a generic part like you describe from their web site. Clicking on Oxygen sensors only prings you to a menu that asks for your car's specifics and, for a Porsche Boxster 01 3.2, that only leads to the Porsche specific part with pigtail attached at $156.

Can you tell us how you found this part? And how you figured out it was the right part # considering that there are 4 O2 sensors that are listed?

Go 4 posts back. I found them at another place (Speedy Auto Parts) for an even better price. I also list the part number if you want to look around for them.

so the sensor is physically the same? it just screws right in to the old socket? this sounds too good to be true
