Improve the performance of your Audi with the IE Aluminum Charging Line Kit, designed for Audi B9 S4, S5, SQ5, and C8 A6 & A7 models. This kit replaces the factory plastic lines, which are prone to breakage and leaks, and provides improved airflow and strength. IE's charge pipes have a consistently larger diameter of 67mm, allowing for a significant increase in airflow compared to the stock 63.5mm lines. This optimizes your engine's power, especially with high-performance and hybrid turbo builds. The kit includes both hot-side and cold-side lines, made of durable TIG-welded aluminum. The in-house machined billet hose ends provide a crush-proof base with grip-lock ribbing, ensuring the boost hoses stay securely in place, even under the most demanding conditions. With its mandrel-bent lines and smooth-flowing silicone fittings, this kit minimizes turbulence and increases airflow efficiency. This system perfectly complements other IE performance upgrades, such as the IE cold air intake and intercooler options. Thanks to the black powder-coated finish, it not only looks good but also remains resistant to rust and wear. Installation is easy thanks to the plug-and-play design that works with both IE and factory components, without the need for any hardware modifications.
