5-Inch Rotomold Polymer Air Intake System

The Integrated Engineering IEINCK5 is a premium polymer air intake system engineered for enhanced performance and auditory feedback on Audi B9/B9.5 S4 and S5 models with the 3.0T engine. The design maximizes internal volume for optimal air supply and smooth flow, utilizing a massive 5-inch air filter and a motorsport-designed velocity stack that minimizes drag and turbulence for high-inertia flow. It is designed to maximize turbo and engine efficiency, resulting in potential gains of up to 19HP and 21 ft-lbs of torque over stock when used with appropriate software. The multi-zone intake design actively channels cool ram air from the grille while also drawing from low-pressure zones through louvers in the filter plate, ensuring sufficient airflow for various power levels and protecting the engine from hot bay air. Beyond power, the IEINCK5 enhances the driving experience by releasing a variety of turbo spool, engine throttle, and diverter blow-off sounds. Installation is designed to be straightforward, utilizing factory-style mounts and basic hand tools, with an estimated install time of 20-45 minutes. For those looking to further optimize performance, the optional cast turbo inlet upgrade is available separately, as are hybrid turbo adapter rings for compatibility with TTE or Pure Turbo hybrid upgrades.
