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

I know I brought this up about 8 months ago and I finally got around to doing it. I went to Parts Train and ordered 4 US Auto Parts Network 4 wire universal sensors for $156 including shipping and I picked up two 8-pair packs of weather proof connectors. I pulled the old sensors out and cut the plug ends off about 6" down the wire. I put the connectors on the wires and plugged them together and plugged the sensors back into the car. Since I put the weatherproof connectors on, next time I only have to put female connectors on a new sensor and plug it in.

They have been running beautifully for the past 2K miles and I'll report back as they age. It sure was nice to replace all 4 sensors for the price of 1 of the exact replacement sensors.

Did you happen to take pictures along the way as you bought and rewired everything?

GOT DAMN! all 4 sensors for only 156 total...did you use that heat shrink wrap stuff to insolate them?

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?
