What's the little black thing that the map sensor hose plugs into for?

Just wondering... I had I off the manifold when I did my injectors and blew through it to see what it does. Air goes both ways and it's got a little bit of restriction through it. What is it for though? A filter? A restrictor?

Anyone know?

Hmm. Interesting. If I had a spare one I'd smash it apart and see what's in there.

I always figured it was a filter also. I have seen them get clogged in camrys, the car ran like crap and it took me forever to find the issue.

Tell that to the person who took the pic. That's the only pic that got close enough to the manifold that it was actually visible that i could find online. lol.
