Skunk2 is proud to introduce the highly anticipated Centerfeed Plenum 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 center feed plenum works best with high RPM naturally aspirated engines and all turbocharged/supercharged applications.

• Cast 356 Aluminum Alloy For Strength And Light Weight
• Symmetrical Bolt Pattern Allows Plenum To Be Flipped
• 3 x 1/8 in. NPT And 3 x 1/4 in. NPT Accessory Ports
• 90mm Throttle Body Flange – Std. 5.0L Ford Pattern
• Modular Design Allows For Easy Volume Changes
• 5L Plenum Volume
