indivisible throttle body

Jordo!

I thought those were largely pointless without a tuned plenum to house them.

Not sure I understand? No plenum is used. You have to tune each ITB to each cylinder.

Meaning, I believe ITB's tend to work better (are easier to tune, yield more consistent idle, throttle response and power) housed within a well designed chamber rather than having each one completely open to the air.

That way you can pipe in cooler air (unless you have them sticking out of the hood), even out airflow, more easily meter airflow, more easily filter, and set up a more stable source of vacuum.
