AUDI 4.0T STAGE 2 INTAKE SYSTEM - S6 S7 RS7

Let your Audi 4.0T turbos finally breathe with the ARM 4.0T Stage 2 Intake System. By removing the airflow restriction feeding the turbochargers, it frees up power, spools the turbos faster and adds an aggressive induction note — ideal for OEM, RS and +4mm turbos.

The system replaces your entire induction setup in two parts: the intake (filters and runner tubes) and the turbo inlets. The inlet portion is the biggest bottleneck in the OEM design, so both must be upgraded together to support Stage 2 and higher tunes — that's exactly what this kit does.

Highlights

• Ideal for OEM, RS and +4mm turbos.
• Gains of up to 27 whp / 32 wtq.
• Faster turbo spool and improved sound.
• Supports Flash Stage 2+ tuning.

What it includes

• ARM full billet inlets: oversized 62mm diameter, perfect from OEM up to +4mm turbos, with the couplers to mate to the ARM intake.
• Aluminum heat shield: seals to the hood and separates cold intake air from engine heat for cooler intake temps.
• 2x dry filters, 2x intake pipes, 2x silicone couplers, 4x T-bolt clamps, 2x worm clamps, 2x 4.0T inlets, 1x aluminum heat shield.
