The RacingLine Trifoam® High Flow Panel Filter is designed for high-performance upgrades on A5-platform vehicles, including the Golf 5 R32, Audi TTS mk2, RS3 8P, and TTRS mk2. This filter serves as a direct drop-in replacement for the factory paper filter, enhancing engine efficiency and complementing both stock and Stage 1 tuned engines.

This upgrade allows your engine to breathe more freely, improving overall performance and efficiency. The Trifoam® filter features a triple-layer design that is reusable and offers superior airflow compared to restrictive factory filters. It meets OEM standards in design and construction, ensuring a perfect fit and long-lasting durability.

Constructed with a stainless steel open mesh and a poured polyurethane moulded seal, the filter provides an airtight fit within the standard airbox. By reducing airflow restrictions, it facilitates a small yet significant increase in airflow to the turbo, leading to potential gains in power and fuel economy.

The Trifoam® material used in this filter ensures exceptional filtration, similar to that used in Formula 1 engines. Testing has indicated that it can deliver an additional 15NM of torque on a standard 2.0 TSI engine, making it a valuable enhancement for performance enthusiasts.
