Skunk2 Racing is proud to announce the next generation of high performance intake manifolds for the Honda B16A B17A and B18C engine or VTEC cylinder heads The much anticipated Ultra Race Intake Manifold is the result of years worth of RD 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.
