Clarks garage refers to this Bosch as corresponding to Porsche part 944 606 135 02. The Bosch is $67 from rock auto, Porsche is $131 from Sonnen.

Is the Bosch identical plug etc? Any reason to pay Porsches price?

Thanks

All Porsche sensors are made by Bosch or VDO


The Bosch part number for the O2 sensor is 0 258 003 011

Right, so you're saying the plug in connector and everything else is identical?

And so paying the Porsche price is only for poor saps who don't know to order the Bosch branded part?

I just want a direct replacement part with no modification necessary. Adapting an equivalent part might be a no brainer for some of you seasoned experts, but I'm not there yet :0)

Thanks

This link will help. You can get a Ford unit for a bunch less and just splice the wires:

Correct


Look at almost any part and its Bosch


Starter

Alternator

Cam sensor

Injectors

Ecu

Abs ecu


Just go to your local Bosch automotive shop and ask for the Bosch part number and its the genuine article

Google Bosch catalog online and then use the car search

there is a difference on rebuilds though.  a bosch rebuilt part is not the same as a porsche rebuilt part.  with a bosch rebuilt, like an alternator, they only replace what they think needs to be replaced.  with a porsche rebuilt, they replace everything.

Thanks everyone great replies

And thanks for the link MCL, I did do a search for oxygen sensor but I guess I didn't look far enough down list to find that thread

I'll be buying the Bosch 02 sensor, hope I don't have as much difficulty getting the old one out as Waylander did

I'm taking the car cross country in June so this is one of those nagging replacements I've been wanting to do for a while

it's actually really easy, if you buy an O2 sensor socket

Regarding the starter, When I bought my 968 from Pete of RS barn in 2010, the starter went bad within 2 weeks of my getting the car cross country, It almost dropped dead completely in the Porsche Sunset driveway, but I managed to get it home. The Porsche starter was $600, I bought mine from a local parts store. It had a lifetime guarantee and only cost me $100. Many parts are interchangeable and can save one lots of money. Oh and Pete stood by the sale and sent me the $100. What can I say but he is a man of convictions.

I'm trying to get the old oxygen sensor out tonight. I borrowed a socket from O'Reillys, it's a 22 mm but it still doesn't fit very tight, partly because it split to get around the wire, and is starting to round the points of the hex on the sensor.

I'm considering sacrificing a feeler gauge to fill the gap. Anybody else have an idea?

My mechanic showed me his O2 socket which had a closed hex on the end and looked like a better tool design...

Thanks,

Michael

Put it on and them put a high quality hose clamp on the socket and really crank it down.

told you they were tight, that's been heated and cooled for the last 20 years and burnt on the inside.

 

I tried two sockets meant for O2 sensors and ended up with a 21 or 22mm ring spanner slipped over the lead and a club hammer

Haha, yep that's what I plan to try tonite; box end wrench (ring spanner) and controlled percussive force (hammer) rather than loading up a cheater bar like I tried last nite.

It's been soaked with PB blaster, but that crush washer might not let it in very well...

"controlled percussive force". Wahahaaa! Brilliant.

Ha well I got the O2 sensor replaced last nite. Turned out to be too hard to control "percussive force" with an inch to spare between my chest and the bottom of the car, so I cut off the open end of my 22 mm craftsman wrench and used the cheater bar. (Actually my go-to cheater bar is the leftover inner cylinder from when I rebuilt my front struts last spring, works great!)

The threads on the old O2 sensor were really rounded, and it was difficult to screw in the new sensor, even with anti-seize grease on the new threads. This must be what Waylander was speaking of when he said he needed to cleanup the threads in the exhaust. I suppose he used a thread tap?

Anyway, the car runs strong, and I'll be checking fuel economy on my next long trip, at the end of june.

Putting together a PDF 'for the record' and will submit later today if this luddite can figure out how to attach the file correctly :0)

 

Thanks again everyone, for the amazing help on this forum. It gives me the confidence to do repairs that I wouldn't have imagined taking on a couple years ago, and I'm usually too cheap to pay a mechanic, so the work wouldn't have been done, and the car and the quality of my driving experience would be the worse for it.

Yes the threads get mushed on the way out with lots of creaking and groans, it will take a short while for the ecu to get used to the new inputs it gets

Would a warm or hot exhaust make the removal easier?

Hi Bulti, I thought about that too, letting the car warm up, but it sounded like a good way to hurt myself, so I wanted to "exhaust' all other options first, LOL.
