What is this Valve?

[Duffman]

I am removing my original air filter and adding the K&N "tuna cans" on my Z. I have determined what to do with the hoses that go into the back of the original air filter housing, but am curious about the valve pictured below. What is it? Did it have something to do with the smog pump (which has been removed)? I am probably going to plug the line from this valve to the original air filter housing, was thinking of removing the valve completely.

Your thoughts?

That's an AB (Anti-backfire) valve IIRC. Some people called them 'gulp' valves. Its a smog thing.

Can be removed and plugged without problems, if you no longer have the smog gear.

Here are three pictures. The first two are pictures are of cars that have been plugged, the third is my red car with everything as stock.

Thanks, Stephen and Arnie for the info.

Arnie, I appreciate the pics, which shows me I can remove a few other things that were originally connected to the smog equipment!
