Injen 18-19 Audi S4/S5 (B9) V6 3.0L Turbo Wrinkle Red Intercooler Piping

If you're looking to get more out of your 2018-2021 Audi S4 or S5's turbocharged V6 engine, this intercooler piping kit from Injen is a solid choice. This kit is designed to replace the stock intercooler pipes, which can be a bottleneck for airflow, especially when you're pushing the engine harder. By smoothing out the path for the air coming from the turbocharger to the intercooler and then to the engine, you'll notice an improved throttle response and a reduction in turbo lag.

Injen builds these pipes from lightweight 6061-T6 aluminum, using mandrel-bent tubing to ensure a consistent, uninterrupted flow. The ends of the pipes are beaded to keep the silicone couplers securely in place, and they use stainless steel clamps with protective liners. This kit includes both the hot and cold side piping, all the necessary automotive-grade silicone couplers, and even a 1/8" female NPT bung for adding a sensor if needed. It's designed as a direct bolt-on replacement that uses all the factory mounting locations and works with your original intercooler, making installation straightforward.

This particular kit comes in a sharp Wrinkle Red finish and includes a unique Injen logo plate for a refined look under the hood. It's made in Pomona, California, and backed by Injen's limited lifetime warranty. Please note that this part is not CARB exempt and cannot be shipped to California or used on vehicles registered there.
