Show original supplier description
The Racingline High-Flow Air Filter is engineered to replace the restrictive factory paper filters in B9-platform Audi vehicles equipped with 3.0 TFSI or 3.0 TDI engines, including the S4, A5, S5, Q5, and SQ5. Constructed with a triple-layer laminate of open-cell polyurethane foam, known as Trifoam®, this filter offers a high-flow design with exceptional filtration capabilities, comparable to technology used in F1 engines. Its non-sealed end design further enhances airflow. The filter utilizes the factory plastic mount for a perfect seal and is supported by a reinforced internal plastic cage, ensuring it fits like a factory part. By removing the inherent restrictions of the standard paper filter, this performance filter allows for a significant increase in airflow to the turbocharger. This improved airflow can lead to better engine efficiency, enhanced power delivery, and potential fuel economy gains. Testing has indicated an additional 20NM of torque on a standard 3.0 TFSI engine, contributing to a noticeable improvement in mid-range power feeling. This air filter is hand-made in the UK to OEM standards of design, quality, materials, and construction. It is compatible with the following Audi models: S4 B9 (2017-2019) 3.0T, S4 B9.5 (2020-2024) 3.0T, S5 B9 (2018-2019) Coupe/Sportback 3.0T, S5 B9.5 (2020-2025) Coupe/Sportback 3.0T, and SQ5 B9 (2018-2024) 3.0T.
