Yeah, no need to yell here.
The best way to tell, IMHO would be to take a look at '05's that are NOT PZEV cert. If they have the screen; but no PZEV rating; then it might actually "protect" the MAF from all of those nasty harmful fumes that every other MAF in history seems to be just fine withstanding without the carbon trap!!!
Just a thought.
