Secondary AIR Injection Pump. Sits atop your Brake Pressure Modulator Valve.

The pump forces fresh air into the exhaust stream in order to accelerate catalyst operation.

no it isn't. It'* a alien space invaders homing GPS beacon (there comming for you)

lol

yeah what he said...

BTW that engine bay is almost as clean as mine

Oh, thank you so much PontiacDad. I had always wondered what that thing was with its exclusive shape. It even has its own steel platform to sit on.

You have a Calfornia car.

there appears to be MANY of the 2000 NAs to be to California specs, including my own, and i believe Jim and Tracy as well, which all have roots in the northeast. I find it odd that so many California spec cars made it to the east coast in the 2000 year

It was at NEBF that me, you, and Boosty were trying to figure out what that thing was on your car.

yeah, i remember that, it was the first time i actually put some thought into it

here is my original thread about it.

As time goes on, meaning model year changes, car manufacturers will tend to cut costs. One cost-cutting measure is to build all cars to the same emissions standard. And since more and more states are adopting Californias emissions standards (which I think has the highest standards in the US), it only makes sense to start making ALL car models with the same emissions equipment. Keeps the amount of "different" parts down, in turn keeping inventory costs lower.

2000 could be GM'* startup year for that kinda plan.

i see that the Buick has the same super soft front motor mount that the 2000 SSEi has. :(
but that can be fixed real easy.

VERY NICE indeed !
