CTS TURBO B9 AUDI SQ5 HIGH-FLOW INTAKE (6" Velocity Stack)

CTS Turbo's high-flow intake system transforms airflow delivery on the B9 Audi SQ5 from 2018 through 2021. Built around a 6-inch velocity stack, this intake replaces the restrictive factory airbox to feed the 3.0-litre turbocharged V6 with significantly more air under load. The design prioritises maximum flow for modified and tuned engines, reducing intake restriction while maintaining smooth air delivery. Engineered specifically for the B9 platform, it integrates cleanly into the engine bay and supports aggressive ECU calibration work. Ideal for performance-focused workshops building reliable SQ5 power upgrades.
