Direct Fit Bosch Oxygen Sensors from Autozone


Recommended Posts

Absolutely Bosch sells to Porsche. The part number equivalences are well known. There is a table at the bottom of this web page. I used the Bosch for one of my front sensors in an '01 with zero problems. Then a year later did the other. Had a muffler shop do the dirty work for $47 each IIRC just because I didn't have a lift handy. Most of the time is waiting for the exhaust/cats to cool down once you have driven onto the lift. The actual work took 5 min max each. These require no specific Porsche expertise. They will require resetting the CEL/Codes with a OBD2 code reader and muffler shops have those and it was included in the price I paid.

Just be sure you are getting OEM sensors not aftermarket. You are asking for trouble if you end up with an aftermarket sensor and not worth it to save $30.00 +. As a CA licensed smog tech I will not even do the job if the customer wants non OEM sensors as I have had too many come back to bite me.

Get them for $100/each from Amazon.com. Yes, Amazon, believe it or not. Found that little goodie in an old Logray post when I did my o2s and sure enough they were exact Bosch matches in the retail box when I got them. I never would have thought Amazon if I hadn't read that. They were quite a bit cheaper than some of the other houses like Vertex or AutohausAZ.

You'd be surprised at the amount of odds and ends you can get at decent pricing from Amazon.......

The upstream and downstream O2 sensors have different length pigtails on them. Do you see any problems with using four of the same O2 sensors with the longer pigtails? I have a MAXspeed aftermarket CAT and the wires are barely long enough on the shorter O2.

Should not be an issue as long as your secure the excess wire out of harms way.

Wow have those prices dropped since I did mine 4-5 years ago. Great suggestions folks.

As for the "don't use OEM" post, who do you think Porsche buys the parts from? Bosch. I think your objection was to generic O2 sensors or ones which don't come with crimped at the factory pigtails. I agree. But in this case the Original Equipment Manufacturer is Bosch.

The Porsche O2 sensors I removed from my exhaust had the Bosch name, the Bosch part number and then Porsche put a Porsche part number on them and put them in a Porsche box.

Yes Bosch is the OEM MFG of Porsche 02 sensors however there are several part numbers available for your application. Just be careful you are getting the correct cross reference part number.

Also there is a TSB from Porsche on the 986 series see below.
