Skunk 2 Ultra Race W/ Ross 90mm Combo

Ross Machine Racing's 90mm bore throttle body is made to the highest standards. Manufactured using CNC machining and is made from 6061 billet aluminum combined with a stainless steel shaft. 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.
