3.5-Inch Supercharged Air Intake System

The CTS Turbo Audi B8/B8.5 S4/S5/Q5/SQ5 V6T Supercharged Air Intake System is engineered for enhanced airflow and performance in V6T supercharged Audi engines. This updated design features a true 3.5-inch velocity stack for maximum air intake, paired with a massive 6-inch inverted cone high-flow air filter. The system aims to improve horsepower and torque across the entire power band, and also provides an aggressive, race-inspired sound. Constructed with a 3.5-inch mandrel-bent aluminum intake pipe finished with a black powder coating, this system is designed to prevent the collapse under vacuum that can occur with silicon pipes, ensuring consistent air flow. It includes a 4-ply silicon connector and stainless steel clamps for a secure fit. An insulated airbox with rubberized trim helps to keep intake air temperatures down, while integrated bracketry prevents rattling under engine torquing. A billet SAI breather adapter with a billet bracket and SAI breather filter is also included. This air intake system is designed to provide peak power gains ranging from 8-11HP on a stock vehicle. However, it is noted that tuned vehicles are pretty much required to run this intake for optimal performance. The system's design prioritizes keeping the supercharger supplied with ample air, thus avoiding choking out air flow. **Vehicle Fitment:** This intake system is exclusively for B8 and B8.5 Audi S4/S5/Q5/SQ5 models equipped with the 3.0T or 3.2L V6 engine.
