screen on TB
Hello can anyone tell me what the screen is for on the T.B.? I did the Upper/Lower intake gaskets (leaking oil into combustion chamber) replaced the upper intake with the new and inproved version and noticed the screen on the TB, kinda strange,,Thanks Mike

In addition, I read some debate about the screen having to do with making the air enter the UIM in a linear fashion and some other design stuff related to how it gets the air and fuel mixed together.

I thought you were just talking about MAF readings. I thought it had something to do further downstream from the MAF....
Sorry, it's been a LONG weekend.

If you have the stock intake box I would recommend keeping the screen on to "straighten the flow" (as others have said)
I personally chose to leave mine on. Some believe that it is a restriction and is not needed if one has a smooth intake which could straighten the flow of the air without needed the screen.

I haven't seen any data that supports removing it will increase flow.
However when I did a TB upgrade, ZZP recommended I remove my screen and retune the car, but if it stumbled a lot to put the screen back on.
