do88 Audi RS6/RS7 C8 Intake System

Filtration, airflow, and heat are the key considerations when designing a new intake system for a turbocharged engine. A turbocharged engine performs best when the air is cool and flows with minimal restriction and low backpressure, and the stock RS6/RS7 intake creates genuine restrictions on a tuned engine, raising air temperature and reducing power. do88's LF-300 High-Flow Intake solves this by reducing backpressure and vacuum, letting the turbos work more efficiently.

The system uses a carbon fibre airbox (base and cover) paired with a BMC High Flow Air Filter, enlarged silicone hoses, and enlarged cast aluminium turbo inlets with adapter rings for either original or hybrid turbos. The result is strong power gains and a more responsive engine, alongside a genuine premium look for the engine bay.

As an option for this intake system, do88 offers OE-style air straighteners designed to fit their turbo inlets, to their knowledge the only aftermarket supplier providing this solution. Manufactured using metal 3D printing, these straighteners introduce slightly more airflow restriction than the standard radius adapter rings included in the kit, but help preserve OE-like power characteristics across the full RPM range and improve long-term durability. Available in two sizes, for OE turbos (54mm) or popular hybrid turbos.

Works with: OEM mounting points. Compatible with OE turbos or hybrid turbo setups via included adapter rings, or optional air straighteners.
