Good luck. I did a small epoxy job myself and it got ripped out last night. I couldnt boost past 20psi.
This is all after I re-did the honetcombs a few days ago (PG1 pics)

I guess it comes with owning a modified car. Something is always bound to go wrong or just not run right. I think it was poorly designed from Mitsu. Although I can see their design ideas and theorys with a venturi type intake. All that it straightening out the air flow is a piece of tin foil. There has to be a high pressure created in the MAS and a low before the screen, which might cause the air to turn or rotate at high speeds (kinda like your toilet flush)

I'm sure that having bent fins in the honecomb don't help things, anything that can alter that straight path of airflow could result in it crushing in on itself like that..
I wanted to point out that its still too big to get sucked into the turbo, but it really sucks, I doubt epoxy will totally solve the problem, but it would be nice if it did.
I have a friend who has a big concern with this happening on his car..
The honeycomb is necessary though, since it allows the airflow to be vectored into the right sections of the MAF (metered air gets metered air, etc..)

You know something, I wonder if its the design of some of the air filter adapters.. Has anyone had this happen with the stock intake box?
It occurred to be that the "Stepping" into the MAF from those flat surfaces may be creating turbulence around the outer perimeter of the honecomb pulling it away from the walls of the MAF ultimately compressing it..

It would seem that there must be a significant difference in pressure on the backside of the honeycomb as compared to the front side. I agree with MalibuJack that the honeycomd probably "bows" in the middle which pulls it away from the side of the MAF. I find it hard to believe that just turbulence would cause this, I think more likely it is a larger restriction that it looks like. There must be a significant pressure difference between each side.
What material is this honeycomb made out of?

Jack- I was wondering the same thing. I was contemplating on putting on the stock air box and doing a test run to see if I can duplicate the incident. But my guess is once the screen is out of place and bent, it will happen again. I cant wait to see what Smogrunner pulls and if it works. Im in the process to do the epoxy job a little better this time and go for some pulls. Id really really like to go racing tonight.

Smog's maf screen went fubar and I'm pretty sure he's on the stock airbox seeing as how he's using an Xede and all....
My screen is slightly boogered from a falling wrench while I was putting on my BR filter...I'm sure it will be a joy in the near future.

We never had any trouble with our red car's MAF, and we ran a factory airbox and MAF. MJ, i think your right. I have a hunch that cone filters create a disruption in the airflow, that upsets the honeycomb. We made 490WHP on our DD, and never had any problem. That MAF is still on the car today ~50k miles.

Hopefully, directly the BOV vent directly toward the compressor will prevent this situation from occurring. If not, it's on to 'Plan B'.

Hopefully it will never be a problem for either of us
