AWE Tuning S-FLO Carbon Intake for B8.5 Audi S4 / S5

The AWE Tuning 3.0T S-FLO Carbon Intake for the B8.5 Audi S4 and S5 is a high-flow, downflow intake system designed to optimize airflow into the 3.0T supercharged V6. It features a lightweight, heat-resistant carbon fiber airbox and high-efficiency air filter element that reduces intake restriction while keeping intake temperatures in check. The system integrates directly with the factory mounting points and MAF sensor, ensuring precise fitment and reliable operation without modifications. By smoothing airflow and minimizing turbulence, the S-FLO Carbon Intake enhances throttle response and allows the supercharger to operate more efficiently, translating to a more responsive engine and consistent performance under both spirited driving and sustained boost.

Massive Filter Upgrade

• At the core of the system are AWE Tuning’s oil-free, washable S-FLO filters, featuring dual inverted cone elements that measure 7 inches long by 6.75 inches wide, with 4.5-inch outlets. These filters are engineered to maximize airflow and offer 142% more filter surface area per unit compared to the factory setup.

Designed to be Heard

• Each AWE Tuning airbox uses an open-face design to capture fresh air from the front of the car, while angled louvers in the lid channel intake and turbo spool sounds into the cabin and protect the filters from engine heat.

Machined Aluminum Connections

• AWE Tuning provides custom-machined aluminum couplers with spring-clamp assemblies to create a secure, snap-fit connection between the intakes and turbos. These couplers are removable to support high-power upgrades beyond stock performance, and threaded aluminum mounting posts align with factory points for seamless integration with OEM inlet ducting.

Power to the Pavement

• The AWE Tuning S-FLO Carbon Intake produces verified gains of 14hp and 9ft-lbs of torque at the wheels on a stock vehicle, requiring no additional tuning.
