indivisible throttle body

Jordo!

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.

Like this Toda High Power ITB Surge Plenum Honda S2000 F20C AP1 S2K [17110-F20-000] - $1,370.00 : Real Street Performance Engine Parts, Pistons Rods Cams Valvetrain and More
