Throttle Body Screen Removal?
I don't see any good reason toyota put a screen/gasket behind the throttle body on the 5.7? It seems to me that the only viable reason for this is to keep debris out of the engine unless it is a minor air flow restrictor? Before you claim BS on the restrictor idea...the 3.4 had a "D" shaped throttle body gasket that restricted airflow between the tb and the intake.
The screen is not very restrictive so removing it would probably not be worth more than a few percent of peak power, but if it's free power, then why not have it all!
Maybe it is some sort or air diffuser designed for the intake to get more consistant air flow to all cylinders???
I know that I took a picture a number of months ago...lets see if I can dig it up.
Others input is appreciated.
