Let me explain the MAF to you. Your explaination, while entertaining, is not even close.
The "hot-wire" MAF does NOT measure air "speed" and the wire does NOT heat the air.
The MAF works like this:
The PCM is programmed to maintain a specific temperature at the wire (sorry, I can't remember the exact temp) and it calculates the airflow across the wire by tracking how much current it must supply to maintain the set temp. The honeycomb screen is there to maintain smooth, even airflow across the wire to minimize the possibility of a sampling error at the wire. Removing the screen will do little if anything for performance. I have read several reports from people that have removed their screen and later found that their idle was left a little rough afterwards. I removed mine and could detect no difference in the idle quality of performance.
You have to understand that much of what is done inside your engine is controlled by outputs from the PCM based on calculations it makes via inputs from several sensors. The MAF is just one of those sensors and it is not even a required sensor to run the car. If you don't believe me, go ahead and unplug it, the car still runs just fine. The OEM backed up the MAF calculations with a version of the previous system. It's called "Speed & Density". It's just a slightly more crude way of calculating airflow but still effective.
