do88 Carbon Fiber Intake System - Audi RS6 / RS7 (C8) 2020-2026

The do88 intake system replaces the factory airbox on the Audi RS6 and RS7 (C8) 4.0 V8 TFSI with a two-piece prepreg carbon fiber housing finished in UV and heat-resistant clearcoat, a washable BMC high-flow filter, enlarged silicone hoses, and cast aluminum turbo inlets. The 80mm turbo inlets are 78% larger than stock and the airbox outlets 57% larger, cutting turbo inlet pressure drop by up to 42% for faster spool and better throttle response. Adapter rings suit OE or hybrid turbochargers, and the kit ships with complete mounting hardware.
