The Skunk2 Racing Ultra Series Intake Manifold offers a high-performance upgrade for Honda B Series VTEC engines, including B16A, B17A, and B18C models. Designed with advanced CFD technology, this manifold features a modular three-piece construction that allows for easy disassembly, porting, and plenum volume adjustments via removable plenum spacers. Its design aims to optimize airflow, resulting in significant torque and horsepower gains over stock and many aftermarket competitors. The 3.5L volume capacity and 90mm throttle body inlet ensure maximum airflow and responsiveness, making it suitable for high-performance street and race applications. The manifold's unique mounting flange is compatible with all B Series VTEC heads, providing a universal fit for various Honda models. Provisions for additional injectors are located on the bottom side of the runners, facilitating fuel system enhancements for boosted or high-output setups. Optional billet aluminum plenum spacers are available in 1L or 2L sizes, allowing further tuning flexibility. The raised 87mm velocity stacks provide ample material for porting, enabling custom flow modifications. Constructed with generously cast runner walls, the manifold is designed to be ported to maximize airflow. The 6.5-inch tilted and tapered high-velocity runners promote efficient air delivery, improving throttle response and overall engine performance. Included with the manifold are a thermal flange gasket and high-grade mounting hardware, ensuring a secure and sealed installation. This manifold is not CARB-legal and requires acknowledgment of non-EMA status, making it ideal for off-road or racing use. Its durable construction, combined with innovative design features, makes the Skunk2 Ultra Series Intake Manifold a top choice for enthusiasts seeking to unlock the full potential of their Honda VTEC engine.
