Sure, here you go:

1997-1999 986 Boxster 2.5L

986-606-126-01 (all four sensors are the same.)

Here is the best site I have found regarding O2 sensors for the Boxster. It is Mike Focke's site.

Hi Boxsterspharm,

I'm not seeing that part number?

Bank 1 is passenger side.

2000-2002 986 Boxster 2.7L or 3.2L

986-606-127-01 - 2000-2002 in front of the starter catalytic-converter - $303.18 retail

986-606-128-01 - 2000-2002 after the starter catalytic-converter - $303.18 retail

You can do better than dealer prices, check Sunset, Pelican or Autoparts Warehouse.

Might consider swapping sides, reset the codes and see what codes appear?

thank you kbrandsma,

so, it is on the passenger side. can you please redefine the behind catalytic converter location of the sensor ( is it front or after the starter catalytic-converter. Is there a picture of which one is which? sorry to ask but I am very new to this.

Here is a photo of your stock exhaust. On each bank there is a manifold that leads to the muffler.

The red dots identify the pre-cat(before) O2 Sensor (#26), the catalytic converter(#2) and post-cat (after) O2 Sensor (#25). The red dots are on the driver's side manifold.
