Basicly what he was trying to tell you.

If you unscrew those 2 phillips and disconnect the sensor, you can pull it out. Then you can clean the little shiny part in the sensor that is shown in the picture attached. It usually gets dirty and is a good idea to clean it every now and then.. esp with a filter like you have there. Those filter doent filter out as well as the paper ones do, but thats for air flow reasons..

I would disconnect your battery again, and clean the MAF sensor. then put it back. Your ecu should reset your learned driving habbits.. You MAY feel a throttle response difference but unlikely. But it doesnt hurt to clean it.
