AWE Audi 4.2L S-Flo Intake | B8 S5

The AWE Tuning S-FLO Intake was engineered to improve the 4.2L V8's ability to draw in cool air while creating impressive power gains.

The AWE Tuning 4.2L S5 S-FLO Intake uses a high flow,4 ply Nomex, fluorosilicone lined, steel wire reinforced silicon air tube to replace the restrictive factory hose. This high flow silicone tube allows cool air to travel freely to the motor. This specifically designed hose is engineered to have optimal flow geometry through the inlet, center section, and outlet of the tube. Furthermore, the silicone hose utilizes a molded lip to ensure a proper seal on both the S-FLO Carbon (or factory airbox) and throttle body for longevity and reliable performance.

The S-FLO Intake includes all necessary installation hardware, and the proprietary S-FLO Filter, detailed below.

S-FLO Filter

The AWE Tuning 4.2L S5 S-FLO Intake uses the proprietary S-FLO Filter, which comes with the S-FLO Intake or S-FLO Carbon Kit, or is available separately. This is a washable, oiled, large cylindrical filter that has been tested to allow up to 34% more airflow than the factory paper filter. The S-FLO Filter is the largest filter that can fit within the air box.

The entirety of the S-FLO line up was designed and tested on AWE Tuning in house vehicles, and are cost effective, incredibly attractive upgrades.
