Racingline Intake System – Audi S3
Part Number: VWR1230S3
The VWR Cold-Air Intake System replaces the restrictive factory intake circuit with an efficient, high flow intake system that utilizes a reusable lifetime foam filter. Developed for use in the Volkswagen Racing Cup where removal of the factory intake is possible, the VWR system delivers astonishing gains as much as 9% greater at peak power than that of the standard intake system. In some cases, turbocharger spool dropped nearly 500 RPMs reducing turbo lag and creating lighting fast turbo response.
The VWR Intake filter is constructed from three layer open-cell polyurethane form, which gives a high level of filtration to protect the engine from contaminants in the air, while not greatly restricting airflow. This same filter material is used by F1 teams around the world due to it’s excellent filtration and airflow properties. In VWR’s experience, cheaper foam filter materials are unable to deliver the same flow and filtration meaning a compromise for your engine.
The VWR Intake System is a ram air style intake, meaning the opening is connected to the factory inlet which draws air directly from the leading edge of the hood. Hot engine bay heat is deflected by the intake housing meaning intake air is only drawn from outside the engine bay. The silicon hose connecting the turbocharger to the intake system features a stepped internal lip, resulting in a smooth transition into the turbocharger, and a continuous clamping force hose clamp allows for even clamping pressure around the entire hose. An optional recirculation bung allows customers with upgraded turbochargers to reroute compressed air from the factory location found on vehicles such as the Golf R, Scirocco R, S3, TTS and Cupra R.
The race bred nature of the intake system is noticeable instantly upon acceleration. The black aluminum housing, with VWR logo, helps maintain sane engine volume levels compared to an open element system, however make no mistake, you will hear the turbocharger compressing massive amounts of air as the engine is able to breathe for the first time. Releasing the throttle under boost will result in a classic turbocharger woosh as the factory diverter valve opens, releasing compressed air from the intercooler piping back to the uncompressed side of the turbocharger. This intake will replace the entire factory engine cover, exposing the engine underneath.
