wow thats pretty crazy..I would be taking a close look at the sealing lip on the lid, and around the bellow to see where it is leaking...

Were you running with no filter? Crazy, one of the reasons I like my clear lid. I can tell if it's a tight fit.

no, look again, took me a minute to figure out, but that tape looking stuff is part of the rubber gasket sealing between the lid and filter, and that's part of the gasket hanging through the lid there! I superglued it back in place...


But anyway, I just drove it again...BINGO!!! It was so freakin' nice, smoth as silk right up to redline and chirps third once again MHUAHAAHAAHAA

best part is, I had an appointment at the dealer today to see if it was a bad cat or whatever. I held off to give myself time to figure it out...saved myself some serious chunk of change there!

I cant imagine all that getting through the lid, it must have not been sealed properly. I descreened my maf and never had any problems with my volant cai.

It didn't get through the lid, it's the weatherstrip from around the lid. Provides the seal. Looks like it wasn't stuck down properly.

I descreend a long time ago and I had the same issue about a month ago. Total loss of power and stalling. The maf was the last thing I checked and saw that the other half of that gasket had already gone into the engine.

You just need a better seal on your air-filter and that stuff won't get up there. I've been running a ported/descreened MAF since 2001 with no problems. I use a Fram and make sure that the lid is tightly sealed.

I say go ahead and remove the screen and port the ends...just keep the seal tight and change your filter regularly. There's no screen on a carbeurator and they've been around forever...

The screen isn't for protection, it's an air straightener for cleaner flow, and removing it will actually HURT your performance. That's why you can't see through the screen unless you look straight on, because it's not a mesh, it's more like a honeycomb.

Sort of....I remember before I bought my Z, doing a lot of reading about these cars, a few years ago...it was debated a lot back then. Back then I was convinced of the theory, and verified it yesterday looking at the screen up close, you can see it's not a woven screen, it has more thickness to it, with very thin walled honeycomb shaped holes...if it was just for a screen, they could have used old-fashioned woven screen much cheaper I imagine. But anyway, it's commonly accepted that it is an air straightener, not a crap catcher...just a bonus that it'll catch big stuff that might sneak by your air filter somehow, as in my case! Can I prove it to you? No...but I do know a lot of people in the know would back me up on this.

That looks like a pretty **** poor lid design. The lid I have fits tight enough that weather stripping is not needed between the lid and filter to assist in sealing.

I removed my screen long ago. The vettes quit using the screen in 2002 I believe.

The screen is in there as a default up to a certain year and it's only really for the types of cars that have bent elbows before the air enters the maf to aid the airflow over the sensors behind the screen. Like the LT1 style cars and the trucks I believe also have a bent elbow.

Shouldn't be an issue if the lid is a good fit.
