The Spoon carbon Kevlar air duct for S2000 routes fresh, cold air to the stock intake box by collecting air from the grill of the front bumper and directing it over the radiator and into the intake box. This prevents the intake from ingesting hot engine bay air and ensures the engine operates at peak efficiency with the best intake air temperature possible.

Developed under street and endurance racing conditions, it was noted that before the air duct was installed, when the engine is exposed to hot conditions, the engine power felt reduced. After installation, the engine is allowed to breathe cold air from the front of the bumper. Installation can be achieved without any modification to the hood.
