The Injen SP cold air intake for 2017–2021 Audi A4 Quattro 2.0T (B9) uses mandrel-bent 6061-T6 aluminum tubing and a SuperNano-Web dry filter to increase airflow while keeping a safe A/F ratio. Dyno-proven gains are around 14 hp and 12 lb-ft of torque; the system isolates the filter from engine bay heat, is offered in multiple finishes, includes all required hardware for installation, and is backed by Injen’s limited lifetime warranty.
