Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I'm new in the world of Porsche and I have recently began probing the market for a 996 C2.
Looking at pictures of the engine bay, I have noticed that the component in the lower left corner (marked with a red arrow in the picture below) is there in some cars while missing in others.
So my first question simply is - what component/system is this (part of)?
Further questions (may or may not be obvious to me when I know the answer of the first question
) - would the presence of this component be model year specific, option specific or else?
Any enlightenment is much appreciated.
Secondary air injection pump. It's a smog component. Definitely required on California cars; I believe it's required on all US-destined cars since all US cars are homologated to CA emissions. It's a blower that adds additional air (and thus more oxygen) to the exhaust stream while the catalytic converters are getting up to temp to ensure "fuller combustion of exhaust gases" and to get the catalysts up to temp more quickly.
If you get a RoW (Rest of world - i.e. anywhere that ISN'T the US) reflash on a car equipped with the SAI pump, you can delete the smog pump and related plumbing.
There are a couple of such items for US-spec cars - I believe the US-Spec '98/'99 C4 has a fuel cooler, while it was not required for non-US markets.
You will also see references to M030 suspension kits being RoW or US-spec. The US has peculiar requirements about ride height, distance of the headlights from the ground, etc.
Cuz goodness knows inches, feet and miles make a lot more since than cm, meter, kilometer. If we don't start getting better presidential candidates Canada might just annex us! Well, the US minus Texas.
Although I've been trying to think of a way for the 49 states to secede from The United State of Texas and saddle them with our national debt. I just haven't thought of what we'd name the new country yet. Taking California with us would be the out big concession at the bargaining table.... Wait, there isn't anyone from California or Texas on here is there?
