How do you descreen the MAF?

I thought I read a post about this a few weeks ago, but I could not find anything on a search. Any help is appreciated.

That metal like screen in the pic? Take a screwdriver to it on the sides until you pry it away just enough to get the screwdriver in there then pry it out.

Takes 5 minutes.

Thanks Big Mike. What's the advantage of doing so? I've had several other Fuel Injected performance cars and I have know about upgrading to a larger MAF, but I have never heard of descreening the MAF.

in all honesty, DONT! That screen is there to protect the filiments inside. That hunk of aluminum is VERY expensive to replace should you muff it up. The advantage is about 50 more cubic feet of air, not worth any real gain.

Its debatable. I've removed them in every GM vehicle I owned. No ill effects. Is there anything to gain? Not sure. It does increase airflow, so with a tune there is probably some gain. The actual reason it is there is to straighten out the airflow for accurate MAF readings. The Z06 MAF does not have one. It has a more direct air inlet which is less turbulant.

It's there for a reason. It's controls the turbulence in the air coming in through the MAF. It's not worth the 5HP to take it out. Just get a tune.

I stand corrected. I always thought it was there to protect the MAF sensors....

In all of GM's vehicles, only the Z06 dont have one. That should tell you something.

Many after market MAF meters do not come with a screen either; however, as someone mentioned earlier they have a different inlet design which allowes a better airflow.

GM engineers didn't just throw it in there to piss us off.
