From my website...

Part Numbers from the Porsche PET

1997 986 Boxster 2.5L

986-606-126-00

1997-1999 986 Boxster 2.5L

986-606-126-01

2000-2002 986 Boxster 2.7L or 3.2L

986-606-127-01 2000-2002 in front of the starter catalytic-converter

986-606-128-01 2000-2002 after the starter catalytic-converter

2003-2004 986 Boxster 2.7L or 3.2L

986-606-227-00 2003-2004 in front of the starter catalytic-converter

986-606-228-00 2003-2004 after the starter catalytic-converter

2003-2004 986 Boxster 2.7L or 3.2L

986-606-226-00 2003-2004 no detail on where used

It is odd that the model year breakpoints donít quite match up in terms of a part number from Porsche equal to the same part from Bosch after 2003 and that there are 3 part numbers listed on page (Illustration) 202-05 of the PET for 03 on. Anyone who can shed some light, please email me.

If I had a 2003 or 2004 Boxster, I'd remove the O2 sensor in question, look for the Bosche part number stenciled on the part and order that as these parts are frequently not returnable.

Part Numbers from Bosch

15738 Oxygen Sensor - Universal Type After Catalyst
2000-2003 986 Boxster 2.7L or 3.2L

15182 Oxygen Sensor - OE Type Before Catalyst

15183 Oxygen Sensor - OE Type After Catalyst

15733 Oxygen Sensor - Universal Type Before Catalyst

15733 Oxygen Sensor - Universal Type After Catalyst

See my comment above on the Porsche part numbers for model years 2003 and 2004. I would remove the old part temporarily and look at the part number on the old part before ordering.

The difference is that the Universal parts do not contain the already fitted wiring harness and you must use the one from your existing and crimp attach (DO NOT SOLDER) it to the new sensor and make the connection watertight. The difference between the before and the after is generally the length of the wiring harness. Better to get the OEM (Original Equipment Manufacturer...the company that makes the part originally and sells it to Porsche who then put their part number on it and stock it as a Porsche part) type made specifically for Porsche. But there is no need to pay Porsche prices. Buy the Bosch ones online. I would stay away from Walker or other generic sensors marketed as working with the Porsche. You can verify the part # at Bosch's site.

Am I nuts? On my 2000 Boxster S, I don't have post cat sensors. I got the car with 14k miles, 14 years ago, and zero mods at that time. Is this correct that I shouldn't have the post cat sensors?

Also, I'm looking at this because I got a P0154 code. I know that is not the post cat sensors.

I note that Pelican sells the Porsche part and the OEM part. I've been working on my Porsches for a long time (Boxster, 911, 912 and 356). I have seen a noticeable difference between the "real" Porsche part and the OEM part - at times. Sometimes it definitely made a difference in the quality of the drive, sometimes it just made my wallet lighter. There is a big difference in price here. Could this be one of those times where there is such quality drive difference? I'm willing to pay extra when there is. That's why I got a Porsche in the first place - and why, for example, I don't get the cheaper tires.

No such thing as a "Porsche part" in this case. Porsche doesn't make O2 sensors. ;)

Jay Laifman 04-26-2017 07:32 AM

Ha! That can be said for pretty much every part. When Porsche orders its parts from vendors, including Bosch, it sets out its specs. Manufacturers can make parts many different quality levels. "OEM" just means original equipment manufacturer. It doesn't mean the original spec part. I've held in my hands parts from the dealer marked by the manufacturer and the same part that is OEM and noted obvious quality differences. But sometimes they are identical. I just don't know if this is one of those times. It could be that the sensor itself is identical, but the wiring and clip are of a lesser quality.

But I will also add that in this case the price difference is quite large. The Porsche price is over 3x the OEM price.

ROW (rest of world) cars don't have post cat sensors, and only have the 2nd set of cats. I don't know if Canadian cars are made to ROW specs or USA (Northamerica?) specs.

What do your exhaust manifolds look like? do they look like this? This is a pic from my car, also a 2000 S.

You can also see the pre and post cat sensors in this picture pretty well.
Or does it look like that without the big bulge in the middle for the cat?

I have just been through this with O2 Sensors and hit a major problem with Bosch/********************************. To their credit I got a prompt refund when I returned the mis-tagged parts.
The problem is the Interchange Manuals. My 'mistake' was to use the Manual to get the Bosch part number and then search for it online. That produced parts that were for a slightly older model and fortunately would not fit.
The safe way is to search by Porsche part number+ your VIN for the Bosch part.Rely only on the Porsche number. Best to use a reliable Porsche-focused source like Sunset or RND Euro Parts.
