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.

FLOW WITHOUT LIMITS

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.

ADD 13% MORE FLOW

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.

EASY UPGRADE. NOT A PROJECT.

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.

Frequently Asked Questions

Does this require a tune?

No. This is a true bolt-on airflow upgrade that functions safely on completely stock software. Because an ECU tune removes factory restrictions and supports higher boost, a tune is required to realize the full performance potential of these pipes, however it isn't necessary.

Will this fit my intercooler?

Yes. This system is designed as a direct replacement for the factory charge piping and fits the stock intercooler as well as any aftermarket intercooler that uses factory connection locations, including the iE FDS Performance Intercooler.

Is this a “throttle pipe” or  “turbo outlet pipe”?

Both! This charge pipe kit replaces the entire air path from the turbocharger outlet to the intercooler, and from the intercooler to the throttle body. For a complete airflow system, pair this upgrade with the iE High-Flow Air Intake and iE FDS Intercooler.

Will this fix a boost leak?

If you’re blowing off couplers or seeing leaks at the factory connection points or O-rings, yes. The iE High-Flow Charge Pipe Kit replaces the stock plastic connections with welded, mechanical Grip-Lock™ pipe ends, heavy-duty silicone couplers, and clamps designed to eliminate the most common Audi B9 boost-leak failure points.

Is there a methanol bung?

Threading into thin-wall charge piping creates a structural weak point. For safer and more reliable water-methanol injection, we recommend using the integrated methanol port found on the thick cast end.

Does this kit work with hybrid turbos?

Yes this product works with all the hybrid turbochargers we have tested.
