PERFORMANCE DESIGN
POWER YOU CAN FEEL
IE engineers have meticulously crafted every millimeter of this intake system, utilizing intricate shapes and angles to minimize turbulence and maximize internal volume. All restrictions are eliminated through performance optimizations, increased airflow, a generous filter surface area, and heat protection for maintaining low intake air temperatures (IATs). This unleashes the true potential of your engine tunes and hardware upgrades to deliver the most performance enhancements possible.
OPTIONAL TURBO INLET
COMPLETE YOUR INTAKE SYSTEM
The IE Turbo Inlet Pipe upgrade removes all intake restrictions and provides a complete high-flow system from the filter to the turbochargers. The premium aircraft-grade aluminum casting and massive 3.2" effective inner diameter deliver impressive flow gains of up to 39.27% over the stock inlet and complete the engine bay with a stylish look. Sold separately.
SINGLE PIECE AIRBOX
STYLE & RELIABILITY WITHOUT COMPROMISE
Enjoy the style and worry-free operation with our seamless one-piece airbox design. Unlike competitor multi-sectioned airboxes, our approach eliminates the risk of air leaks, complicated installation, rubbing noises, and parts loosening over time while maintaining the smoothest internal airflow path.
UNIQUE SOUND
ENJOY YOUR THROTTLE PEDAL
Sound is as integral to your driving journey as power. Immerse yourself in the addicting symphony of turbocharger spool, engine throttle, and diverter valve noises that resonate from your twin-turbo RS engine. Unlike the factory airbox that suppresses all sound, our intake system embraces the excitement with a refined and exhilarating audial experience that perfectly complements the enhanced performance of your build.
VELOCITY STACK
UNINTERRUPTED POWER
Uncommon in consumer-level applications, our integrated velocity stack strategically amplifies and smooths flow dynamics at a vital point as air enters the charge system. This advanced design element provides a gradual reduction from the substantial 5" air filter to the smaller turbo inlet. By precisely controlling this crucial transition, our intake system accommodates increased turbocharger and engine airflow demands with minimized drag and power-robbing turbulence.
DUAL AIR-ZONES
AIR SUPPLY FOR ANY POWER GOAL
Our carbon airbox is equipped with multiple air supply avenues to support various power and build levels. The front and expansive air inlet captures outside high-pressure airflow and acts as a ram air design. Additionally, the filter plate louvers draw in extra air as required from the low-pressure zone below the intake. These dual zones provide an unrestricted air supply across the entire filter, eliminating power limitations for even the most extreme builds.
TECHNOLOGY DRIVEN
QUALITY IS IN THE DETAILS
Our team of experts utilize cutting-edge 3D scanning tools and software to capture the precise dimensions of your vehicle's engine bay, grille, bumper, and hood. These high-resolution scans create an exact digital duplicate, enabling our engineers to harness every inch of available space with utmost precision. By leveraging this digital environment, we ensure a flawless design with the perfect style, fit, and feel.
PERFORMANCE VALIDATION
The IE Performance 2.9TT Air Intake System has been power tested to deliver impressive gains of up to 28HP and 26ft-lbs on tuned engines (with stock turbos)! Feel the surge of performance as you take command of the road, leaving ordinary RS5 and RS4s in the dust.
FLOW BENCH TESTING
Back-to-back flow bench results show constant and consistent CFM gains of up to 39.27% CFM over stock! This increase in flow details the intake design's efficiency over the factory parts and capability to provide any required airflow demands from ECU tunes and hybrid turbocharger upgrades.
