Is the intake screen important?

Subject: Is the intake screen important? Fri Apr 17, 2009 9:30 pm

I was doing a BG fuel induction service, and in the process had to remove a c-clip that was holding in a flimsy screen that is in front of the mass air flow sensor.
I can think of three possible reasons for it being there:
Cut down on intake noise
Stop large particles that may have circumvented the air filter
Diffuse the air coming in, so that it blows onto the mass air flow sensor at an even rate as the rest of the intake.

If it is there for the latter reason I should leave it. The other two reasons I'm not worried about.

What is your take?

It is the latter reason, leave it in, just clean it gently with Mass Airflow Sensor Cleaner (aerosol can) and a soft toothbrush if it is very dirty. I have used this cleaner made by CRC.

What Rick said. Be careful not to touch the sensor wire inside the MAF body when you spray it clean. Let it dry completely before installing, it dries quickly though.

That's why it's there. Better off to leave it there.
