IE Aluminum Charge Pipe Kit For Audi B9 S4/S5/SQ5 3.0T

The IE Aluminum Charge Pipe Kit for Audi B9 S4, S5, & SQ5 eliminates factory bottlenecks and weak plastic materials for increased flow and strength. Our TIG-welded individual billet hose ends provide a reliable crush-proof base with grip-lock ribbing to keep boost hoses securely in place in even the most demanding performance and hybrid turbo builds.

Increase Flow

IE charge pipes are performance engineered to eliminate the stock-equipped intercooler piping's small diameter, pinched sections, and abrupt bends. Our increased 67mm consistent sizing and smooth flow path remove any possibility for flow restrictions or power limitations from the charge piping on performance builds.

Reliable Materials

Say goodbye to cracked plastic, inferior materials, and boost leaks for good. Our kit replaces both the hot and cold side piping with mandrel bent and TIG welded aluminum charge pipes for maximum durability and performance. We've also upgraded the couplers with strong five-ply smooth-flow silicone couplers and stainless clamps, ensuring a complete and lasting upgrade.

Billet Hose Ends

Typical aftermarket charge pipe designs roll a bead into the end of the thin aluminum pipe, which can crush under hose clamps and lead to boost leaks. Our charge pipes feature individual billet thick-wall hose ends TIG welded onto each pipe end for maximum durability. We took it further with machined grip-lock ribbing and radius ends to ensure your boost connections stay secure under the most demanding high-boost builds.

Perfect Match

We've developed our charge pipe upgrade to perfectly complement our intake, turbo inlet, and intercooler options, providing a complete and optimized charge air system from the intake to the throttle body. With your existing IE hardware, your new charge pipes are an easy bolt-in job.

No hardware upgrades are required to install charge pipes, and this kit will work with IE brand or stock components. Compatibility with non-IE brand hardware parts is not guaranteed.

Precision Engineering

IE engineers optimize performance in the available space using 3D scanning tools and rapid prototyping. This cutting-edge technology and meticulous attention to detail ensure a perfect, factory-like fit without interference or annoying rattles.
