General Fake Bosch LSU 4.9 sensors

I’ve been looking at a replacement wb sensor and I see a lot on eBay for around $40. Are these fake Bosch sensors?

As per my tuner, those are in fact fake Bosch. He also mentioned something about using a '05 350z Bosch WB sensor. They're probably cheaper in the auto parts store. I've yet to buy one, so I can't confirm for sure.
He works for AEM , so he definitely knows his stuff.

I purchase replacement sensors through local auto parts stores. Volkswagen also uses Bosch wideband sensors in some of their cars, just make sure you get the correct sensor (4.2 or 4.9), so cross-reference the part number. My replacement was @ $55 with a online discount. It also comes with a 1yr replacement warranty.

Just looked it up and they're pretty expensive.

I like that price point. Do you have a link? I hate ordering wrong parts.

I have used the Volkwagon sensors also. They plug right in and are the same unit. Only reason I replaced one was I oiled it down when I broke a turbine shaft and mosquito fogged for about 5 miles, coating everything inside the exhaust pipes. Boy what a experience.

Saw this on Amazon. It says not original but made to over OEM specs and LIFETIME warranty.

Woahhhh Lifetime warranty???

20% for one star and they all have pretty much the same complaint.

I haven't ever got a non Bosch sensor Tony but wanted to see what was being offered. I found my sensor at Oriellys and it was in a Bosch box so I felt good about that.

gotcha!! I’m contemplating getting an aem x series. My current sensor takes about 30 seconds to heat up and the reading at times jumps from 14-18 for a sec cruising. My VE table is pretty smooth and I have a feeling it could be the sensor. This all happened after I bought a set of injectors from ecmlink forum that had one injector completely stuck open so it dumped a ton of fuel. Probably close to half a gallon and caused an error 8 iirc. Recalibrated it and it’s been like that ever since.

Yeah I'd venture to say it is fuel contaminated and be thinking of changing it like my oil soaked one. It was fine but I didn't trust it after twisting that shaft into two.

I wasn't aware any car used a 4.9 sensor stock. Last time i tried to fine one they could only get 4.2 sensors from parts stores and had to order a 4.9 offline.

Think I figured out why afr was going lean for a sec. One of my injector was stuck closed. Got it freed up so we’ll see.
