The #1 power-adding bolt-on upgrade for your 4.0T! The ARM 4.0T Inlets greatly improve airflow to your turbos by replacing the restrictive OEM inlets. Upgraded inlets for the 4.0T are so essential that most tuners list it as a required upgrade for any tune above a base Stage 1 tune.

Installing the ARM 4.0T Inlets will eliminate any induction restriction on your 4.0T, allowing your turbos to spool faster, generate more low-end torque and produce higher peak HP for snappy launches and high trap speeds!

The ARM 4.0T Inlets directly replace the OEM inlets on the S6, S7, and RS7. The ARM 4.0T Inlets will fit any turbocharger setup that uses the OEM inlets. The ARM 4.0T Inlets are substantially improved over the RS inlets, which have a smaller diameter than the ARM 4.0T Inlets.

CONSTRUCTION

To vastly improve airflow over the OEM inlets while still making this a direct replacement, we utilized a 6-Axis machining process to produce the largest piping possible in the space available. This process was required to contour the inlet piping as to maintain 63mm diameter piping throughout the entirety of the inlets. The result is the largest inlet piping possible while keeping an OEM-like setup.

The machined inlet flanges transition to 63mm aluminum piping, extending to the 6-Layer reinforced silicone couplers. These couplers are extra durable to prevent deformation during induction on demanding builds.

Connected at the other end of the silicone couplers are the J-Pipes from the ARM 4.0T Intake.  The ARM 4.0T Inlets are designed to be paired with the ARM 4.0T Intake, which extends the air filters deep within the passenger side airbox cavity to access the coolest air available in the engine bay.

Note:

Unless you plan a custom setup, the ARM 4.0T Intake is required to properly fit the ARM 4.0T Inlets, as the ARM 4.0T Inlets do not include air filters.
