Skunk2 Racing is proud to announce the next generation of high performance intake manifolds for the Honda D16Z6 and D16Y8! The much anticipated Ultra Race Intake Manifold for the single cam D Series is the result of years worth of R&D and building upon the performance legacy of our Pro Series Intake Manifold. Using the latest in CFD (Computational Fluid Dynamics) software; Skunk2 Racing has created a three-piece modular design that allows for easy disassembly, porting, and plenum volume changes through the use of a removable plenum and optional plenum spacers. The result is a design that is less restrictive, yielding both torque and power gains well over many of the competitors.
