Audi B9/B9.5 RS4/RS5 Performance Air Intake
Free up the induction side of your Audi RS4 or RS5 with this Performance Air Intake — a high-flow cone filter and heat shield kit engineered to increase airflow, sharpen throttle response, and add a genuine induction note under load.
Designed specifically for the B9 platform twin-turbocharged V6, the kit replaces the restrictive factory airbox and paper element with a large washable cone filter. The powder-coated heat shield keeps the filter separated from radiant engine bay heat and channels cooler air in from the factory duct, so the intake charge stays denser under sustained load.
A reinforced silicone coupler and stainless clamps join the filter to the factory turbo inlet, and the whole kit mounts to existing locations — no cutting, no permanent modification, and fully reversible.
The simplest and most cost-effective airflow upgrade available for the 2.9T V6, and an ideal first supporting modification alongside a downpipe or tune.
