CTS Turbo Audi B8/B8.5 S4, S5, Q5, SQ5 V6T Supercharged Air Intake System (True 3.5" velocity stack)

The CTS Turbo air intake system addresses the restrictive factory airbox on supercharged 3.0 V6T Audi models. Engineered specifically for B8 and B8.5 S4, S5, Q5 and SQ5 variants, this system incorporates a true 3.5-inch velocity stack design that optimises airflow directly into the supercharger. The precision-engineered velocity stack promotes smooth air transition while reducing turbulence, allowing the forced induction system to operate more efficiently. Built for Australian workshop installation, the complete system replaces the standard intake assembly with direct OEM-grade fitment across all applicable model years from 2009 through 2016.
