Indeed there are! About three different threads.
Very amusing ....

The Bosch seems to be $5 more.

Yeah, for some reason the generic is a couple dollars more, plus your local autoparts palace is likely to have the Ford for sure.

Yeash....that was me trying in vain to have a meaningful ( and "understandable") dialogue with a Bosch Engineer who used to frequent this board.

We really got nowhere when he *insisted* that the reference O2 signal was via the air path through the insulated wires...implying of course...that if you splice/solder the connections...that air resupply path would be interrrupted and corrupted.

I tried to give him the benefit of doubt and ( curious that I am for *truth*) kept egging him on for more details....supported by some sort of FACT that I can understand.....

Didn't work....he left in a huff .....

Sorry Wil, no disrespect intended there at all. You (and most others on the board) know alot more about cars than I do.

It just sounds strange that the reference oxygen signal occurs via the insulated wires. Perhaps that's true in the OEM engineered versions of the O2 sensor.

It seems to me that the Bosch engineers would consider this when offering a universal setup where cutting/soldering/and shrink tubing is explicity in their instructions.

Or something like that.

Anyone know the Part Number for the Ford Sensor ?
Or what year and Model Ford ?

So what I infer from this is that: Generic vs. OEM....

Because it's labeled "OEM" then it commands a significant markup rather than being specifically engineered for the Porsche....

Hey Wil...

I gotta believe that there was something lost in the translation/conversation with that Bosch engineer...Air through the insulation??? I wonder if he completely understood the issue...Doesn't make sense...

kqw:

If you find the thread you will see there was NO misunderstanding.....both he and I were very clear, but he didn't follow up with any form of convincing argument why/how what is says can possibly be true. He asserts that the reference "air" signal under the wire insualtion needs an unimpeded path righ back to the DME unit.

I then countered with.."What about the connector in the engine compartment?. The wire "ends" there and another wire ( to the mating connector) runs back to the DME...."
See ? No confusion. But he never explained hinself fully.

That aside..if you find the thread...you'll see all kinds of Ford and Generic parts numbers...that are still valid as best as I can tell...

Wil

Wil, as always, I'll take your word for it...

Never take my ( or any other's) "word"....

Best to judge for yourself after reading this.....

PS-- no offense taken on any of this. Sometimes "mining" for the truth leads you down a rough path...that's all :)

That's one of the beauties of this board...people disagree with each other all the time, but 99% of it (with the possible exception of certain people with strong opinions on chips) is in the spirit of getting information out to people so they can make informed decisions on their needs.

Wil, I never bought into the "air thru the wire" scenario in the old thread, but I found it interesting and give you credit for pushing the Bosch rep to support his contentions.

I put a Walker generic sensor in my 86 two years ago...works great with no problems. Mixture is fine.

I check out oxygensensors.com

they have nothing on 88' 911 which one would work for me?

As far as I can tell the generic three wire can be used on 911's between the years of 1984 - 1994?

Please someone confirm this.

I would also try again as I get the same page as for 86 or 87 ...

Not always, well not at least for the 964 and 993 (i have no idea if it applies to the 3.2). The genuine Porsche O2 sensor is plunge-proof and the OEM Bosch units aren't.

what is "plunge-proof"?

Based upon my nerve-wracking dialogue with the Bosch Rep ( re: the "other" posts on this...) ...I don't think this assertiion is correct. The Bosch units ( either generic or made-for-Porsche) should be water tight and the replenished reference "air" ( if such is the case)...does not come from an open port to the atmosphere....rendering it "plunge-proof".

If you dig into the dialogue...you'll find that NTK... or others... might indeed fit...but may also have this "open" port that needs very deliberate splash shielding.

Not wanting to wait for shipping and looking for instant gratification, I just bought and installed the Bosch unit 13593, which has 16" leads. Everything is great! Interestingly one parts store recognized the part #: 0258003953 While the other recognized 13953 as the correct number. The O2 sensor was $42 (autozone & Kragen). total time to solder the leads, cover with shrink wrap and install the unit, about 1 hour.

FWIU the proper "generic", Bosch sensor is the same sensor as OE less the specific harness plug. The generic sensors come with a well designed solderless splicing kit which you use with your own plug. I used it on four sensors for a '97 Twin Turbo and it worked perfectly.

The generic part numbers are available at the Bosch site via their part finer.
