CTS Turbo Intake for Audi B9/B9.5 A4, Allroad, A5, S4, S5, RS4 and RS5 Models
The new CTS Turbo intake for Audi B9/B9.5 A4, Allroad, A5, S4, S5, RS4 and RS5 models features a redesigned closed air filter housing manufactured using rotomoulding technology, as well as an air intake duct with an air deflector that efficiently directs outside air into the intake system.
Air flows through a large 6-inch high-flow velocity stack air filter and continues through a smooth-surfaced 3.5-inch five-layer silicone turbo inlet pipe to the engine. The design helps reduce flow resistance while maintaining excellent fitment and durability.
The closed air filter housing manufactured using rotomoulding technology effectively isolates the filter from engine bay heat, while the CTS Turbo air deflector feeds fresh outside air directly into the system. All components of the CTS Turbo intake system work together to improve engine power and torque across the entire rev range. At the same time, the intake air sound is enhanced and becomes clearer. The turbocharger spool-up and bypass valve operation are also slightly more audible than before. This intake is designed to be efficient, and the increase in sound level it produces is moderate.
In a stock car, the intake system has achieved a power increase of up to 15 hp. Programmed cars can achieve even greater improvements.
