I have not...But I would certainly give it a try....It is nothing more than electronic paint sniffer anyway

Good luck.

I think if your car is stock, you should be ok. As soon as you are modded/tuned, I think you might want to stick with better 02's as the readings will be more sensitive. My 02...lol

 

I personally wouldn't do it. These cars use closed loop fueling which means the ECU is always measuring the AFRs at all times and constantly making adjustments. If the sensors are skewed for any reason, your AFRs will be off, possibly by a significant amount. That can lead to motor issues or failure. There are other places to save a sixty bucks...this isn't it, IMO.

 

Generic no, but a few weeks ago I had the 4 O2 sensors in my 996 Turbo (132K miles) replaced and the tech (an ex-Porsche dealer senior tech) told me the Bosch boxed sensors were just as good as the ones in the Porsche box so I had him install the Bosch sensors. The Bosch sensors were less expensive than the Porsche sensors but I don't know the difference, though I kind of recall it was substantial.

The engine feels a mite peppier after the new Bosch sensors were installed, but I suspect it would have felt just as peppy with new Porsche sensors, too. Like plugs and coils Turbo engines are harder on O2 sensors.

I mention this peppy point only to point out at least with the non Porsche sensors there was no fall off in the way the engine felt.

Whether the Bosch sensors deliver the same service as the stock Porsche sensors only time will tell.

I would not go so far as to use "generic" sensors. I have nothing more to go on that just a suspicion that while one can get the same quality for something less in this case Porsche labeled sensors that at some point when the price drops too far down the very cheap hardware is just not the same as the more expensive hardware.

Just a feeling, opinion, but I'm not willing to experiment with my car's engine to find out.

 

Note ....The O2 Sensor in the OP question is not GENERIC. The part number is a Bosch.

His thread title says "Generic", but the link in his request that he was asking about is a Bosch number. (Part# 17307 99760612802 ) - Guarantee it is no different than the Porsche one...other than part number. I had the same deal with Coils. Part numbers cross reference to the exact same coils...Only I did not get a Porsche logo on my box...

Oh yeah, big difference between the same parts branded with the manufacturer name vs Porsche, and generic ones. The Bosch 02 sensors are what are used stock. If you can cross match and verify the correct Bosch sensor to the Porsche part #, then go for it.

Like therock, I have Beru branded coils in my car. They don't say Porsche, but Beru is one of the manufacturers of the coilpacks for Porsche.

Just like LUK makes most OEM flywheels

 

those are post cats not pre....also bosch is the same as oem porsche brand. If you purchase the bosch ones, they have a bosch part number and also a porsche part number stamped on them. The post cats are actually going for about 100 shipped for the pair on amazon...

nvm...realized these are for 997's but the same applies with the bosch sensors.

 

my upfronts are 17307 bosch havent installed yet. any idea if these work?

apparently FCP euro sold me these for twice the price


for my pre-cat 997TT O2 sensors. praying to god these work!

 

Absolutely not. "oe supplier" is exactly how no brand junk gets listed. If the seller doesn't say bosch, it's not bosch. The part number means nothing. If it's ebay, and it does say bosch, hopefully it's bosch, but it's hard to be sure as counterfeiting is real. Be very careful where you buy things. It's not worth the headaches to save $20. Anything on ebay is suspect until proven otherwise, and should be evaluated extremely carefully. If it's a brand new part and is way under cost compared to reputable sellers, then thats a giant red flag. If it's 5$ cheaper, it could still be fake. pay the 5$ and get it from an authorized reseller.

The bosch knockoffs wholesale for 4$. 4 freaking dollars and they are making a profit on that.

Do not buy that (likely) no name garbage. A bosch part number does not mean bosch. No name suppliers use bosch part numbers to indicate interchangeability. Be sure you are getting Bosch.

I'd consider buying a bosch part from a reputable seller. this may be fine and notice how it doesnt look like what you posted.
Amazon.com: Bosch 17307 Oxygen Sensor, OE Type Fitment: Automotive

 

The ones I picked up are BOSCH 17307, german parts. length was a little different than the ones I pulled out, but these seem to fit fine.

 

I tried those exact genuine Bosch 17307 ones from Amazon..despite being labeled as an exact part match, they are too short (by about 8 inches) and do not have the grey silicon boot for extra heat protection. i returned them and got the genuine Porsche ones from sonnen... Fit perfect and cleaned up the lambda deltas in my logs..

 

that goes to a poor install. You either have to be able to keep the wire spinning with the sensor on install or you need to pre-twist the wires counter clockwise so that when you tighten the sensor the exhaust, the wires unwind.
