Features all ball bearing support of the longitudinal throttle shafts, including the bearing between each set of butterflies. This gives super smooth throttle action, allowing better control of the car on the track.   These manifolds can accommodate any port design the customer wants.  Kinsler can help the customer select a port for his engine combination, by varying both the shape and volume of the CNC ported runners.   The manifold was released in February, and Kinsler has already made some extreme variations to suite their customers.  Some have been made for EFI road racing and for street use, with throttle position sensors, fuel rails, and nozzle bosses for EFI nozzles.
