Enhance your Honda Civic's performance with the Skunk2 Racing Ultra Series D Series Race Intake Manifold. Designed specifically for Honda Civics from 1988 to 1995 with D16Z6 and D16Y8 engines, this high-performance intake manifold delivers significant power and torque gains. Its 3.5-liter plenum volume and 90mm inlet size optimize airflow, providing improved throttle response and overall engine efficiency. The manifold's black finish adds a sleek aesthetic to your engine bay and withstands high temperatures for durability. Built using cutting-edge CFD (Computational Fluid Dynamics) software, the Ultra Series manifold features a modular three-piece design that facilitates easy disassembly, porting, and customization through removable plenums and optional spacers. This flexibility allows mechanics and enthusiasts to tailor the intake to their specific needs, whether for daily driving or racing applications.

Incorporating four secondary injector bosses, this manifold supports additional fueling options for high-performance builds. The manifold's design includes a 90mm inlet compatible with early 5.0L Ford throttle bodies, making it versatile for various tuning setups. While not CARB-legal, it is suitable for off-road and racing use and requires acknowledgment of Prop 65 regulations. The durable construction ensures longevity under demanding conditions, and its precise fitment guarantees seamless installation on compatible Honda models. Whether you're upgrading your stock intake or building a track-ready engine, the Skunk2 Ultra Series manifold offers a combination of innovative design, performance enhancement, and customization potential to elevate your Honda Civic's capabilities.
