Yes... soo... I don't know how much higher flowing. I realize the Fiero doesn't really have a breathing problem from the factory side scoop (at least the stock 2.8 V6 doesn't according to several tests). But I ran across this air cleaner lid at the junkyard several years ago. For the life of me, I absolutely cannot remember what car it came from... it was like a Buick or some such.
Anyway, it is the identical size of the Fiero's V6 air cleaner canister (I remember test-fitting it). I don't have a V6 Fiero in front of me right now to see, but I'm almost 100% sure that the lid is exposing the inside of the air filter, which is where we want the air to come from.
I picked it up just in case as I thought it might be a kind of cool thing to use if someone wanted to install some sort of vacuum operated vent-area additional intake. You'd simply need a threaded dowel that was long enough (just a little more than an inch longer than the factory one). Obviously, I know there's hot air in there, but I'm assuming if someone were to use this, they'd likely have ceramic coated headers or header wrap, etc.
I'd imagine something like what I had in my 82 TransAm... you floor it, and with the increased vacuum coming from the engine, it flipped open a cowl flap allowing additional cooler air from the top of the air cleaner.
Posting here in case anyone finds it interesting...

Cool, one thing though, I think it would be closed with vacuum, open with less vacuum, as when you floor it, manifold pressure gets closer to ambient and vacuum forms when the throttle closes.

I've copied the entire post by Todd just to demonstrate how unnecessary it is to copy the entire post simply to respond. Do we really need to see everything that was originally posted, including the images?
1985 Fiero GT, I'm not trying to pick on you, but this thread just happens to be a blatant example of what we're unfortunately witnessing here on a more regular basis. I suspect it has to do with more and more people accessing the forum through their phones... but whatever the reason, it's detrimental to the forum experience, having to scroll through numerous copied and re-posted text and images that serve absolutely no purpose whatsoever.
In regards to the air filter canister lid (which we get to see three times now ), the only way I envision that it could be even minimally useful in a Fiero application (perhaps one with a swapped engine that needs more air) is if cool air from outside the engine bay was ducted to the opening in that lid.

Sorry about that, never thought about that, you're likely right about it being from phones though, exactly what I'm using now!

You know, I honestly don't remember now. I'm not going to argue with you... I was a software engineer before I became a person that sends e-mails all day, so you're probably right. But I seem to recall in my 82 TransAm that the flap was closed when parked... intentionally because it would prevent rain from getting in (it was basically a conduit directly into the air cleaner, with a small run-off for rain). When you'd floor it, it would open up. But my 81 TransAm, which had a shaker hood, that actually had an electronically controlled solenoid. But that **** never ran so I couldn't tell you... hahaha... I think there was a momentary switch on the carburetor that engaged along with the secondaries.

Hahah Patrick, I don't mean to be mean... but I've learned personally the old adage that when people get older, the stop caring what people think and start speaking their mind more often... or just doing whatever the hell they want. I remember the last time I was with my dad in Washington D.C., and he started opening the emergency exit doors to walk between the subway cars. This might be something people do in NYC... but damn that is like... you do NOT do that in the D.C. Subway. That's grounds for arrest. My dad couldn't have given a damn. People were looking at him, and he just swore in Dutch and made his way past people on the subway into the other car... and there were gasps. I was like... **** dad... (and just followed him), hahah.
So yes... I was going to make a joke about how you're old because you're doing this from a PC... but I am too. I can't stand using mobile devices. Meanwhile my daughter would rather watch a movie on her iPhone with earpods (or whatever they're called), than our 80" 4K TV in the family room.
But yeah, it would obviously need to be cool air, which if you're driving probably wouldn't be too bad. I'd love to figure out what the temperature is of the air passing through the decklid vents at speed. Worthless for a 2.8, but if you were trying to keep a stock look, and had something on top that looked relatively stock to allow a little bit of extra air in... I'd be interested to know if it does anything, or if it's still bottlenecked even by a larger throttle body (assuming DAWG mod and everything else, on a 3.4).
It would likely end up being one of those $500 for 1 hp kind of solutions.

Yes that's how it is, you just got confused on when there is vacuum (throttle closed) and when there is none (floored) so it might have some spring trying to open it, and a vacuum diaphragm fighting the spring to keep it closed, when there's vacuum, it's closed, when there's no vacuum, it's open. Probably with some work around for when the car is off, and there is no vacuum being generated to keep it shut.

It's not a high flowing Air cleaner cover, it's from a FWD application that has a hood intake design. 89-94 Cavalier Z24's have a lid with the center completely open. This style is no benefit to a Fiero, probably a detriment as it would certainly suck in that baking hot air in the engine bay.

Shoot, you just looked at the pictures and the title didn't you, haha...
I said if you can get past the hot air (fabricate something) and use it with the stock air canister (for which it fits), you could get air coming from both the top and the bottom of the filter canister.

If wanted "more air" w/ OE Fiero V6 air cleaner... RD make/made a mod kit to open up the section holding the cover bolt. I doubt actually helps w/ OE & most swap engines.

Worse, let all kind of crap dropping into the filter from air vent above it. IF still have Fiero box bottom etc. then might plug that in time from crap from above.
Many fools rip out the wall in the separator box to "get more air" only causes problems including destroy V6 air filter driving on wet roads.
see https://www.fiero.nl/forum/.../HTML/144683.html#p3 How intake air muffler works...
Most Air filters Hate getting wet & polluted water close the "pores" & stay close after drying. Even a new clean filter will restrict air flow after getting wet.------------------
