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. Design w/ Removable Plenum * 3.5L Plenum Volume** * 90mm Throttle Body Flange - Std. 5.0L Ford Pattern * Tapered Hi-Velocity Runners * Raised Velocity Stacks * Generously Cast Runner Walls for Porting * Provisions Secondary Fuel Rail & Injectors * Hi-Grade Mounting Hardware * Thermal Gasket Included * Fits MOST Popular Chassis Configurations - Not Just Race Cars (See Notes)
