Description

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 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.Features:Modular 3pc.
