Default What is it?

Changing my headlights out today and noticed a loose vacuum line. Traced it back to this. Located on the driver side front of the engine bay right behind the headlight.It looks like it has a nipple where it may have connected at one point but the Nippleis rusted out. What is it? And are they readily available whatever it is.

Nissan refers to it as an IACV or pair valve, try this pt# 14828-30P00 (just the round valve), 14812-86G00 is the whole case

That is the pair valve, it injects air into the exhaust stream to assist in lowering emissions. By now the filter inside has turned to dust.

that's the one that sits on top of the reed valves, the air filter should be in round case (maybe 8" dia)

That just sounds like cheating lol. Like mixing water with a piss test to dilute the sample.

I know it's in the black round canister on the inner fender, doesn't change the fact the filter is dust thus compromising the system.
