The iE Polymer Air Intake System delivers performance, sound, and style to your Audi B8 S4 or S5 3.0T engine. Our specialty polymer construction maintains low intake air temps and brings an affordable motorsport design to your engine bay. Enjoy bolt-on power gains and supercharger noise without sacrificing quality. POLYMER ADVANTAGE This cold air intake is manufactured from a high-quality rotomold manufacturing that produces a superior plastic material with consistent wall thickness, strong corners, and excellent heat resistance. Enjoy a proper motorsport-designed intake system without compromise. BREATHE FREE The stock airbox on your Audi S4 or S5 has been manufactured to silence all engine and supercharger sounds at any performance cost. Upgrading your air system with an iE polymer intake will release a symphony of whine and engine throttle sounds that will be music to your ears. THROTTLE BODY UPGRADE For those looking for every ounce of power, this intake kit is direct install with the iE 3.0T Throttle Body Kit. Your throttle body kit will include a larger inlet silicone adapter that creates a perfect high-flow transition from the intake velocity stack directly to the new 80mm throttle body. No modifications or extra adapters are required. iE Throttle Body Kit sold separately. HIGH VELOCITY The integrated velocity stack smooths the airflow from the large filter into the charge system with excellent laminar properties. This powerful design detail results in a very high inertia flow with reduced drag and power-robbing turbulence at the critical point as air enters the turbocharger. MULTI-PRESSURE ZONES This intake features high and low pressure zones to supply the supercharger and engine with enough airflow for any power goal demands. Fresh air from the front of the vehicle is forced into the intake through the grill. Additional air demands are pulled from from under the intake from the endless supply of air behind the bumper. The intake shields the filter from the hot engine bay air, always delivering the lowest temp air available. POWER TESTING Countless design revisions, rapid prototyping, flow bench testing, dyno runs, and real-world verification has resulted in a performance intake design with power gains of up to +21 WHP on tuned engines! FLOW RESULTS Flow testing confirms consistent airflow gains up to +73% CFM over the stock setup, allowing your engine to breathe freely at any power level. By increasing airflow and volume, our intake design ensures smooth, unrestricted power delivery from ECU tunes and performance hardware upgrades. EASY INSTALLATION Flow testing confirms consistent airflow gains up to +73% CFM over the stock setup, allowing your engine to breathe freely at any power level. By increasing airflow and volume, our intake design ensures smooth, unrestricted power delivery from ECU tunes and performance hardware upgrades. Average install time around 20-30 minutes PRECISION DESIGN 3D scanning tools are leveraged to create a high-resolution digital environment allowing our engineers to take advantage of all available space for a complete performance design while ensuring a hassle-free install.
