    What is this between the lid and the TB?

    What is this thing which I've colored brown? is it needed for anything? can I just delete it and connect the lid to the throttle body?

    Also... I see people say, get a lid... is this the stock one that everyone replaces?

    Forget the name but it quiets the air flow. When you get an aftermarket lid the air being sucked in going wot is much more noticeable.

    that is part of the lid i believe it is some kind of baffle ( not sure my car had an slp lid when i got it) and yes i would replace it with an after market piece they are much less restrictive

    It is called a Helmholtz Resonator. It is designed to cancel out standing waves in the intake tract and reduce noise. What that really means is it keeps your car from performing like it should -- ditch it and pop on an aftermarket lid.

    The "lid" is the part before the Helmholtz resonators and is a separate part of the air intake tract.

    Guess I need to add "Junior Klugscheisser" to my profile in place of "Junior Moderator".

    Seems like all the work you did you would have been better off and cheaper spending 90 dollars on a new lid.

    Actually the inside of the slp and all other "smooth" lids is just that: smooth, i.e., no reinforcing ribs like the stock lid has. Also, in order to have it work most effeciently you need to remove part of the base and cut out part of the separator to allow more air to flow into the lid.
