Description

FLOW WITHOUT LIMITS

Audi equipped your B9 A4 or A5 with squished, irregular, and restrictive plastic charge pipes. The iE High-Flow Charge Pipe Kit removes those compromises with smooth, mandrel-bent aluminum engineered to channel air cleanly and let the turbo breathe and sound the way it should.

ADD 13% MORE FLOW

Your factory plastic charge pipes feature abrupt bends and poor internal transitions, disrupting airflow and reducing turbo efficiency. The iE Audi B9 charge pipe upgrade replaces every restriction with smooth, mandrel-bent aluminum, delivering up to 13% more flow than stock and providing clean, consistent airflow from the turbo to the throttle body.

TURN UP THE SPOOL

Audi molded a disappointing resonator chamber directly into the factory charge pipes to kill turbo sound and add yet another airflow restriction. Don't worry - this upgrade removes it. You’ll finally hear all those hidden spool and turbo sounds set free.

GRIP-LOCK CONNECTIONS

Shallow bead rolls on other aftermarket designs are why charge pipes leak, blow off, and are generally make these products a hassle. Our charge pipes feature our proprietary CNC-machined Grip-Lock ends that mechanically bite into the couplers, keeping them locked in place even under serious boost.

EASY UPGRADE. NOT A PROJECT.

Where generic, Alibaba and Temu parts rattle and rub, iE charge pipes are engineered to fit with millimeter-perfect precision. We 3D-scanned the engine bay and obsessively prototyped the system to retain factory mounting points, clear all components, and install with basic tools. This is what "bolt-on" is supposed to feel like.

BUILT TO SCALE

Designed to integrate seamlessly with the iE Air Intake System and FDS Intercooler, improving airflow across the entire charge system while supporting higher boost, ECU tuning, and larger turbo upgrades without becoming obsolete.
