Air Pump Removal; What's this piece?

Someone bumped an old thread of mine on a different forum, and I thought i'd re-ask it here.



I was in the middle of removing my air pump (07 STI) and I wasnt quite sure what this piece is, where it goes, and what to do with it?

The pump had a rubber y-hose coming off. One end went to a selonoid with the atmospheric pressure sensor, and the other end went to the thing i circled above. It appears to be a tank or something in there, but its hard to get to and see.

The y-pipe here:

I was under the impression that with 07 STIs there was only one air injection port on the heads; am I mistaken?

It seemed impossible to get out without removing quite a few more hoses, and potentially the manifold, so i just capped it. I'm still curious about what it might be and where it might go.

The 07 STi only has the air pump going to one head. That hose in question can be removed

I wish it could! I tried and tried and it wouldn't come out. If/when i take my IM off i can get in there i suppose.
