Audi C8 RS6 RS7 Black Carbon Intake

The Eventuri carbon intake for the Audi C8 RS6 and RS7 is a complete redesign of the airbox, built around two goals: more flow and smoother airflow. The engine bay is tightly packed under the bonnet, so Eventuri redesigned the whole airbox to use every bit of available volume, enlarged the openings where air enters, and set the filter at a more favourable angle to the turbos than the 90-degree turn of the stock box.

The airbox is organically shaped around a custom rounded BMC panel filter, with no sharp corners in the airflow path, so the flow stays laminar from filter to turbo. The turbo inlets are up to 85% larger than stock at the airbox side and taper smoothly down to the stock turbos. On Eventuri's flow bench the complete system flowed 90% more than the stock airbox and inlets. The gains grow with the state of tune, because a tuned engine asks more air of the turbos.

Key Features:

• Complete airbox in pre-preg carbon fibre: base, lid and enlarged turbo inlets
• Lower airbox combined with the slam panel for more volume
• Lid shape developed with CFD simulation; the best of four tested designs
• Bespoke washable 4-layer cotton BMC panel filter with a larger filtration area than stock
• Turbo inlets up to 85% larger at the airbox side, with CNC-machined reinforcement
• EPDM couplers that allow engine movement while keeping the flow smooth
• Separate inlets for hybrid turbos available on request

Performance:

• Stock ECU: +15 to 25 hp, +11 to 20 lb-ft (approx. +15 to 27 Nm)
• Stage 1: +45 to 50 hp, +40 to 45 lb-ft (approx. +54 to 61 Nm); 100 to 200 km/h 0.6 s quicker
• Stage 2: +60 to 80 hp, +60 to 70 lb-ft (approx. +81 to 95 Nm)
• Figures from independent tests by Awesome GTI (UK) and Eurocharged (Canada); gains vary with the ECU tune
