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.

The engineers at Skunk2 Racing have worked tirelessly to develop the next generation of high performance intake manifolds and are proud to announce the release of the much anticipated Ultra Series Intake Manifold. Years of R&D have culminated in a multi-piece cast aluminum intake manifold that offers advantages that only a modular design could allow. Following our Ultra Race B & K Series Intake Manifolds, as well as 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. In addition to CFD testing, the Ultra Series Intake Manifold has undergone extensive in-house dyno and on-car testing which has led to a design that is less restrictive, yielding both torque and power gains well over many of the competitors. Ultra Series Intake Manifolds are made from high-grade 356 aluminum alloy for a strong and lightweight design, CNC-machined for a precise fit, and individually inspected for quality assurance. The large 90mm throttle body opening, 81mm velocity stacks, and hi-velocity intake runners with smooth transitions allow the Ultra Series Manifold to outflow the competition. Designed to be used with built, high-horsepower naturally aspirated or forced induction setups, the Skunk2 Ultra Series Intake Manifold helps provide a new level affordable high-end intake technology to the marketplace. 1L and 2L Plenum Spacers upgrades available.

12-15 hp gains with Skunk2’s Tuner Series Drop In Camshafts, our professional line of high-lift, racing camshafts for Honda’s K-series VTEC engines. Tuner Series Drop In Camshafts are designed to optimize mid-range and top-end horsepower and torque, with peak power moved up the RPM band. As a result, VTEC crossover is seamless, allowing for the broadest powerband possible. No other line of racing camshafts even comes close to Skunk2’s Tuner Series. Whats more, Tuner Series Camshafts are also the perfect addition to any high-output, turbocharged engine. Skunk2’s Tuner Series Camshafts for Honda’s K-series engines dramatically increase both horsepower and torque yet retain complete valvetrain stability and exceptional engine response. Ideal for heavily modified engines, Tuner Series Camshafts are manufactured from proprietary, high-quality forged tool steel cores, are CNC ground, and feature patent-pending profiles with unique lobe shapes and revolutionary lift, velocity, and acceleration characteristics. Skunk2 camshafts deliver unparalleled power as a result of continual, extensive development and testing. By utilizing advanced manufacturing techniques and the latest computerized simulation and modeling equipment, Skunk2 camshafts are able to deliver maximum power across the entire powerband. Skunk2 designs and tests all of its camshafts in-house to ensure the highest quality and performance. Each camshaft is manufactured of forged tool steel core, increased torsional strength, improved durability characteristics, and reduced frictional effects. All Skunk2 camshafts are ground to exact specifications using state-of-the-art CNC cam grinding machines equipped with cubic-boron grinding wheels and feature hardened, wear-resistant lobes and surfaces.
