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

The 2018-2021 Audi S4 and S5 with the V6 3.0L Turbo engine are known for their performance, and this Injen intercooler charge pipe system is designed to help you get even more out of it. This kit replaces the factory hot and cold side intercooler piping with smooth, mandrel-bent 6061-T6 aluminum tubing. This design creates a more direct path for air coming from the turbochargers to the intercooler and then to the engine, helping it breathe easier.

Crafted from lightweight 6061-T6 aluminum, the tubing features beaded ends to ensure the included automotive-grade silicone couplers stay securely in place, even under boost. The precision CNC machined and TIG-welded sensor flanges ensure a solid mounting point for your factory sensors, and the kit uses all factory mounting locations for a direct bolt-on installation with your OE intercooler. This updated piping can lead to improved throttle response and a decrease in turbo lag, making the car feel more responsive when you press the accelerator. It also includes a 1/8" female NPT bung, which is useful if you plan to add a boost gauge or water-methanol injection system later on.

This Injen intercooler piping kit comes with all the necessary hardware for a straightforward installation, including stainless steel band clamps with protective liners. It's made in Pomona, California, and is backed by Injen's limited lifetime warranty. While this kit is designed to work with the factory intercooler, it pairs exceptionally well with Injen's cold air intake systems for even greater performance gains.
