The Skunk2 Racing Ultra Series D Series Race Intake Manifold is engineered for high-performance Honda applications, including popular Civic and Del Sol models from 1988 to 1997. Crafted from high-grade 356 aluminum alloy, this manifold combines strength and lightweight construction to enhance your engine's airflow capabilities. Its CNC-machined precision ensures a perfect fit, while individual inspections guarantee quality and durability. Designed with a modular, three-piece construction, it allows for effortless disassembly, porting, and adjustment of plenum volume with optional spacers, offering customizable airflow tuning for various high-horsepower setups. Extensive CFD, dyno, and on-car testing have optimized this manifold to minimize restrictions, resulting in notable torque and power gains over many competitors. The large 90mm throttle body inlet, 81mm velocity stacks, and smoothly transitioning hi-velocity runners improve airflow efficiency, enabling increased engine performance whether naturally aspirated or forced induction. The manifold is compatible with a 5.0 Ford bolt pattern and includes a thermal flange gasket and high-grade mounting hardware for secure installation. Its design is suitable for a wide range of chassis configurations, making it an ideal upgrade for enthusiasts seeking affordable, high-end intake technology. Optional 1L and 2L plenum spacers provide further performance tuning options, ensuring this intake manifold meets diverse engine build requirements.
