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

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

[ohioboxster]

Well, I was just going to buy 4 of them and a new maf but I went to check out and the shipping was $35.00 give me a break! I went online with a live customer service chat and they still wouldnt budge. They lost a 400.00 plus sale over greedy and inflated shipping. That was Parts train by the way. Im going to check the other site now. If thety dont try to rip me off I will order from they.

All O2 sensors are basically the same. They give a reading to the DME in milli-amps (IIRC) based on the temperature of the cats and the DME adjusts fuel/air mix depending on that reading. The only difference between O2 sensors is the number of wires. I believe they are all the same physical size, but I'd rather be cautious and make sure you check the threads before you just go out and get them. I also bought a Bosch universal sensor from someone on eBay that's made for the Honda Civic for $15. It matches my original sensors too.

Holy cow! The shipping I paid was around $15. I thought it was high at the time, but still so much less than the regular ones I took the deal. I never checked their MAF price. Is it pretty good too? I paid $245 for an MAF at Sunset so I'm interested in the differences.

I ended up buying an 02 sensor from speedy auto parts, just one. I tried everything I could to buy four but it just kept going back to one in my shopping cart. My scanner says I have one bad 02 sensor so I will just start with that one. Bought the MAF from Pelican for 280.00 and free shipping I trust them.
