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.
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 5.5" 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.
