What is the purpose of the screen that comes stock in front of the Mass Air Flow Sensor? AND, is there an advantage to removing it with a . . . dare I say it here . . . MAC CAI (modded, no bend)?

I don't know exactly what it does although I would assume it just keeps large particles from getting sucked through the intake into the plenum, ect. When I installed my K&N intake the directions told me not to re-use the screen so I guess it doesn't do much. I doubt there would be any advantage to removing it.

I don't know what large particles could get through the filter and need to be screened

someone said before that it straightens out air and reduces turbulance. makes sense to me.

I seem to remember this same explaination too. Unfortunately, it's very restrictive and even if it does straighten out the air, it would again encounture turbulance when it goes thru the stock rubber accordian tube with the big dimple in it, near the TB. (I just got a good look at this myself today while digging through a box of old OEM parts - JonJon, was it you who had pointed out the big dimple in this thing? You are so right, it's major!)
Buy a C&L MAF kit and Trueflow pipe...problem solved.

Can you remove it without destroying it? And can you put it back if, for whatever reason, you have idle problems or something freaky? If the answer to these is Yes, then I'd say go for it! And I'd be interested to hear if it made a difference. Best of luck!

i took it out when I installed my C&L MAF, no problems.

I took mine out (02 GT) when I installed the Volant CAI, seems to run fine !

89 has a C&L meter and runs fine also

All 1.5 ounces of it

I was the one who said the turbulence theory. Lets do a test, I could always be wrong. Someone remove it and then drive the car around for 5 miles or so and report power gains/losses and any idle problems

I would leave it on because it smoothes out the air turbulance in the MAF then again would send the right air fuel ratio readings to the computer, therefore you wouldn't have any idle problems like I did, I felt no performance increase with it removed. For some people, they have no problems with the screen removed.

here's the deal, from experience...

the screen only smooths out the airflow on a PAPER FILTER. the meshed K&N filter already does this by it's design, so you dont need it. i took it out back when i had a paper filter and i had idle problems. i took it out when i dropped in the KN and no problems. best bet is to take it out, just breathing through it isnt as strong as if it wasnt in there. if you remove it though, remove the rubber seal around it and place the seal back in there, just remove the actual metal screen. to be honest, i felt a definate difference with my DR induction tube with K&N, no screen, and keeping the stock airbox with no snorkel. it's very similiar to the FIPK systems that cost 240 bucks . it restricts some of the hot air but still flows very well.

It straightens out the air from axial air rotation so the MAF can properly read the amount of air comming in the engine. If you take it off, there's a good chance nothing will change, but in some cases the car runs crappy. I did a lot of research on it, and came to the conclusion: Leave it alone.

I disagree with a bunch of the above. Look at that thing. There is no way it provides any impedance to airflow, and you will see no gain at all if you remove it. It is certainly not "restrictive". I took one look, and realized I'd wasted my time even considering removing it.
