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 don’t 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

1997-1999 986 Boxster 2.5L

13806 Oxygen Sensor - OE Type Before Catalyst

13806 Oxygen Sensor - Universal Type After Catalyst

15738 Oxygen Sensor - Universal Type Before Catalyst

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

15738 Oxygen Sensor - Universal Type Before Catalyst

15738 Oxygen Sensor - Universal Type After Catalyst

2004 986 Boxster 2.7L or 3.2 L

16506 Oxygen Sensor - OE Type Before Catalyst

15506 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.
