Oxygen senors replacement

[boxster boy 16]

Hey guy's my Boxster was throwing p-codes. I located the p-codes and they happened to be the oxygen senors. I purchased the USOS -4000 senors. They will run you about thirty dollars apiece. You just have to put a little more elbow grease when installing them however; you will still get the excellent result of no check engine lights. Was really excited about the results just wanted to post this and let you guys know. :D

How long have you had them installed? I tried those same exact o2 sensors when I had a 99' Boxster - I had gotten a code for one of my o2 sensors and decided to replace all 4, after I installed them and reset the check engine light, the check engine light came back on about 20 miles later saying all o2 sensor were bad. I ended up purachasing Bosch OE ones for significantly more money which worked fine.

You can buy

Porsche branded with wiring, Bosch branded with wiring, Bosch without wiring, Walker without wiring, generic without wiring.

I like to use one with wiring of the proper length already installed by someone who knows what they are doing and who does it using a multi-thousand dollar machine especially made to do flawless crimps and who tests the unit in ways I can't before they ship it out.

If you can do a flawless wiring job that can provide the proper signal for 40k miles or so, congratulations.
