Audi S4 Performance Air Intake – APR Open Carbon Fiber (2010–2016). This open-element system replaces the factory airbox to improve airflow, sharpen response, and add a richer supercharger note.

The stock system is undersized at higher output. APR’s drop-in intake removes the airbox, using a carbon-fiber air-dam to feed a 7-inch cotton filter with a frontal inlet. A T304 stainless-steel heat shield and air gap help manage engine-bay heat, while the 4-inch inlet mates to the factory tube or APR Ultracharger for a clear path to the supercharger. In APR testing, flow-bench gains reached up to 268 CFM at 28" H2O over stock, supporting average gains of 17 AWHP on Stage 2+ (93). Installs in minutes.
