Technical Information

The rotomolded polymer airbox provides excellent thermal insulation while maintaining a lightweight and durable construction. An integrated 5.5-inch velocity stack creates a smooth transition into the supercharger, reducing turbulence and improving airflow efficiency.

Performance

The dual-pressure intake design draws cool air from multiple sources while shielding the intake from radiant engine heat. Combined with ECU tuning, the system supports gains of up to 25 HP and delivers a noticeably more aggressive supercharger sound.

Installation

The intake installs using factory mounting locations without permanent modifications. It is also fully compatible with the IE 80 mm Throttle Body Kit, which installs without requiring additional adapters or modifications.

Notes

Not compatible with early Audi S5 models equipped with the naturally aspirated V8 engine. The IE 80 mm Throttle Body Kit is sold separately.
