The ARM Motorsports Audi 4.0T Inlets are direct-replacement turbo inlets for the C7 and C7.5 Audi S6, S7 and RS7 with the 4.0T V8, replacing the restrictive OEM inlets. They are produced with a 6-axis machining process to hold 63mm piping throughout, with machined inlet flanges leading into 63mm aluminium pipe and 6-layer reinforced silicone couplers, and ARM says this is larger than the RS inlets. The brand quotes gains of 27whp and 32wtq, faster turbo spool and improved sound, and says most tuners list upgraded inlets as a requirement for any tune above a base Stage 1 tune. They fit any turbocharger setup that uses the OEM inlets, and they do not include air filters, so ARM designed them to pair with its 4.0T Intake.
