Description

RacingLine VWR I 1241S4 Carbon Fibre Intake System is engineered for Audi S4 and S5 B9 models powered by the EA839 3.0 TFSI turbocharged V6. The system retains the factory lower airbox and adds a formed carbon-fibre lid, reusable high-flow Trifoam filter and dedicated cold-air scoop to improve the path of fresh air into the engine.

The fully enclosed design helps isolate the intake charge from engine-bay heat while keeping induction volume controlled during normal driving. Under load, the larger filter area and more efficient airflow path deliver a richer induction note and support the increased airflow requirements of tuned vehicles. The matte carbon construction also provides a high-quality, factory-style engine-bay finish.

RacingLine reports that the improved intake efficiency can reduce turbo spool by up to 500 rpm in some applications; results depend on vehicle specification, calibration and operating conditions. This SKU is for S4/S5 3.0 TFSI models and is not the RS4/RS5 2.9 TFSI version. Inspect and service the filter regularly using products suitable for RacingLine Trifoam media.
