Show original supplier description
The CTS Turbo air intake system is engineered to maximize airflow for Audi 3.0T and 3.2L FSI engines. This updated design features true 3.5-inch mandrel-bent aluminum piping with a black powder coating, paired with a massive 6-inch velocity stack air filter. The inverted cone design of the filter ensures maximum engine breathing, and the insulated airbox with rubberized trim helps maintain lower temperatures. The system integrates with the OEM air scoop and a sealed airbox to force cold air into the intake. It includes a 4-ply silicon connector with stainless steel clamps, bracketry to prevent rattling, and a billet SAI breather adapter with a billet bracket and filter. Gains of 8-11HP are reported on stock vehicles, and tuned vehicles are highly recommended to run this intake. This intake is exclusively for B8 and B8.5 Audi S4/S5/Q5/SQ5 models equipped with the 3.0T or 3.2L V6 engine. It is not for sale or use in California on any pollution-controlled vehicle as per the California Air Resources Board.
