The iE Polymer Air Intake System redefines your Audi B8/B8.5 S4 or S5’s driving experience with impressive power gains, thrilling supercharger sounds, and a sleek, motorsport-inspired design. Crafted from high-performance polymer, this intake delivers cooler, uninterrupted airflow to your engine, maximizing performance while offering effortless installation with factory-style mounting.
LOOKS THAT PERFORM
PERFORMANCE. SOUND. PRECISION.
POLYMER ADVANTAGE
Engineered with rotomold polymer, this intake delivers superior heat resistance and durability while maintaining a lightweight and cost-effective design. It's the cost effective innovative intake system delivering true motorsport performance without compromise.
UNLEASH THE WHINE
Stock airboxes suppress your Audi’s true personality. With the iE Polymer Air Intake, every throttle blip and supercharger whine becomes an orchestra of pure performance sounds that will be music to your ears.
INTEGRATED VELOCITY STACK
Our built-in velocity stack transforms airflow, creating a seamless transition to the engine for maximum power and efficiency. This smooth segue reduces drag and power-robbing turbulence at the critical point as air enters the supercharger.
DUAL AIR ZONES
Fresh, cold air flows freely from multiple sources, with high and low-pressure zones working together to deliver uninterrupted airflow directly to your supercharger. Cool air is forced in through the front grille, while the open-bottom design pulls additional fresh air from behind the bumper. The intake is shielded to block radiant heat from the engine bay, ensuring only the coolest air enters the system for maximum performance.
THROTTLE BODY READY
Pair your intake with the iE 3.0T Throttle Body Kit for even more power. The iE 80mm Throttle Body Kit includes a larger inlet adapter making it a direct fit to the iE Polymer Intake System, further maximizing airflow. No extra parts or modifications are required.

PERFORMANCE DATA
REAL RESULTS, PROVEN GAINS
DYNO RESULTS
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!
Performance data was collected during controlled testing on our own in-house dyno facility. Multiple back to back runs were performed on a dual pulley stage 2 B8 S4 in exacting conditions; the only change made to the vehicle between runs is the swap from stock to the iE Polymer Air Intake System.
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.

The above gains are a result of various design details:
- The 5" air filter surface area and increased air volume improve efficiency.
- The internal velocity stack provides a low-turbulence transition.
- High & low-pressure zones channel low-temp airflow quickly to the engine while protecting it from radiant engine heat.
