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

Injen is known for making well-built intake systems that help engines breathe better. For your Audi S4 or S5 with the V6 3.0L turbo engine, this intercooler piping kit is designed to take that performance a step further. It replaces the factory piping with smoother, larger diameter tubes, allowing your turbocharger to push more air into the intercooler and then into the engine. This means you get improved throttle response and less waiting for the turbo to build boost.

The heart of this kit is the mandrel-bent 6061-T6 aluminum tubing. Mandrel bending means the tube maintains its diameter throughout the bend, unlike crush-bent tubing which can restrict airflow. This smooth, uninterrupted path helps keep the air cool and consistent, which is crucial for turbocharged engines. The kit includes both the hot and cold side piping, and features beaded ends to ensure the silicone couplers stay securely in place. It’s designed as a direct bolt-on replacement for your OE intercooler, making installation straightforward. This particular version comes in a sharp wrinkle black finish, and Injen backs it with a limited lifetime warranty.

This kit includes all the necessary hardware for installation, including automotive-grade silicone couplers and stainless steel clamps with protective liners. It also features precision CNC machined and TIG-welded sensor flanges, along with a 1/8" female NPT bung for custom sensor or boost gauge setups. While this kit is designed to work with your factory intercooler, pairing it with an Injen cold air intake can unlock even greater performance gains.
