Skunk2 Honda B- And K-Series Ultra Race Intake Manifold Applications - Ultra Race Centerfeed Plenum

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

The centerfeed plenum works best with high RPM naturally aspirated engines and all turbocharged/ supercharged applications.
