RacingLine High-Flow Panel Air Filter / Audi S4/S5 B9 3.0 TSI

The perfect starting point for your Audi B9's 3.0 TFSI power upgrades, RacingLine's Trifoam® High Flow Air Filter uses the exact same filter material as our intake systems do. A simple drop-in replacement for your factory paper filter, giving a valuable boost to engine efficiency as a perfect complement to either the stock engine or those running Stage 1 calibrations.

Looking for a simple, warranty-friendly upgrade for your car? Set your engine free by allowing it to breathe better and operate more efficiently with RacingLine’s High-Flow Air Filter, available for all 3.0 TFSI turbocharged cars. It replaces the restrictive factory paper filters with an improved, high flow and reusable lifetime triple-layer Trifoam® filter. Put simply, it’s the best Panel Air Filter you can buy. This filter offers OEM-standards of design, quality, materials and construction, hand-made in the UK. Fits like a factory part; lasts like a factory part. A stainless steel open mesh, surrounded by a poured polyurethane moulded seal provides an airtight seal against the standard airbox. Removing the inevitable restrictions that the standard paper panel filter gives, RacingLine’s Panel Filter allows a small but worthwhile increase in airflow through to the turbo. And by allowing your engine to breathe better and operate more efficiently will improve the engine’s airflow, and power and fuel economy gains will follow. The Trifoam® filter material itself ensures an exceptionally high level of filtration – it’s the very same material technology as some F1 engines use. Our tests have shown that it can deliver an additional 20NM of torque on a standard 3.0 TFSI engine. A small but very worthwhile difference.
