Skunk2 Ultra Race Intake Manifold Centerfeed Plenum Conversion Black K B Series K20 B16A B18C Vtec

Skunk2 is proud to introduce the highly anticipated Centerfeed Plenum Black for the Honda B and K Ultra Race Intake Manifolds! 

The Ultra Race Centerfeed Plenum has been designed to further improve airflow and reduce lean conditions associated with side-fed manifolds, by moving the throttle body forward and centering it above all intake ports. The centerfeed plenum works best with high RPM naturally aspirated engines and all turbocharged/ supercharged applications.
