Interesting, wonder why they are only on the S model?

Anyone have some insight on why the S model has them and the Base doesn't?

Are you sure about that? I'm sitting here pretty confident my 02 base has the secondary 02....maybe I'm remembering wrong....

Edit - sorry, quoting the wrong response....

Was actually last Sunday
But I changed spark plugs, spark plug tubes and oil. Will flush coolant and replace thermostat with the low temp one in the next 2 weeks.

I'm pretty sure it's year dependent whether or not your secondary cats have O2 Sensors.

What get's me is the 2003 Base doesn't have them according to EJ-Fresno and my 2003 S does have them.

The Porsche PET doesn't show them as S model specific. If they were they would put M008 in the Model column. M008 stands for 986 S 3.2 Litres Displacement.
