Overview

The ARM Motorsport Audi 4.0T Inlets are an upgraded component designed to improve airflow to your turbos. They replace the restrictive OEM inlets, allowing turbos to spool faster and generate more torque and horsepower. These inlets are a direct replacement for the OEM components on the S6, S7, and RS7, and will fit any turbocharger setup utilizing OEM inlets.
Show original supplier description
The ARM Motorsport Audi 4.0T Inlets are engineered to be the #1 power-adding bolt-on upgrade for your 4.0T engine. By replacing the restrictive OEM inlets, these components significantly improve airflow to your turbos, enabling them to spool faster and produce greater low-end torque and higher peak horsepower. This results in improved acceleration and higher trap speeds. Constructed using a precise 6-axis machining process, the inlets feature 63mm diameter piping throughout to maximize airflow. The machined inlet flanges transition to 63mm aluminum piping, connected via 6-layer reinforced silicone couplers designed to withstand demanding conditions. The inlets are designed to connect to the J-Pipes of the ARM 4.0T Intake system and do not include air filters; the ARM 4.0T Intake is required for proper fitment. Installation of these inlets is recommended for any tune above a base Stage 1 tune, as they eliminate induction restrictions. The ARM 4.0T Inlets are a direct replacement for the OEM units on the Audi S6 (2012-2018), S7 (2012-2018), and RS7 (2013-2019), all equipped with the 4.0T V8 engine. An optional ARM 4.0T Heat Shield is available to further optimize intake air temperatures by separating cold air intake from engine heat.
