Throttle Body Gasket Screen?

I believe those honeycombs are there to straighten out the air or something like that so that the MAF sensor has an accurate reading. Not 100% sure on that tho. But I think that's also the same reason why K&N had some kind of flap in their intake pipe.

I believe you are correct. Hopefully removing it won't cause erroneous readings.

Seems like there's a lot of confusion on the web about it:

It's there for a reason, even if it's not publicly visible. =)

Interesting reading. I wonder about the spark arrestor function as it only covers about 1/3 of the opening. But, for sure, Toyota put it there for a reason. I think I'll leave it in place.
