    Default Air intake chamber??

    Not trying to fix anything here cause nothing is broke. BUT...Does any one know what the purpose is of that bulbous chamber that resides on the underside of the plastic runner from the MAF to the throttle body?

    Can you provide a picture of it? Is it attached to the air tube? Are there any connectors or lines running to it?

    Hmmm. I see. It is probably there to catch any moisture that passes by the filter. If you take the rubber tube loose, can you see if the air is forced to pass down through it and back up before getting to the throttle body? It may also be a "muffler" to keep air suction noise down.

    Nope, no air through it, just a hole in the bottom of the duct. my thought was a muffler of sorts also, some engineered chamber to attenuate some odd frequency noise that showed up in testing. It cost money to put it there so it must be of some use.

    It's a muffler to cut down intake air noise, you'll find them on almost every vehicle manufactured now days.
    In my opinion I think it's a waste, I've removed them on every vehicle I own, doesnt change mileage, sound, or performance.

    tbplus10 is on the money. It's a sound dampener (a resonating chamber is more likely to be an accurate term, either way, the point is it dampens sound). The chamber changes the acoustics and softens the roar of the engine. Basically, makes it a touch softer so you're not drowned out in the cabin.
