Description
Overview
The AWE Tuning S-FLO Cold Air Intake is engineered for the 2008-2012 Audi S5 (4.2) and built for drivers who want an intake that performs and looks the part. Designed around AWE Tuning’s S-FLO Edition architecture and assembled in the USA, this air intake system replaces the restrictive factory setup with a purpose-built, high-flow path to the engine — delivering cooler, more consistent airflow without the need for a tune.
At the heart of the system are three primary components working together: the washable, reusable S-FLO Filter; a high-flow, 4-ply Nomex®, fluorosilicone-lined, steel wire reinforced silicone air tube; and a 2×2 twill carbon fiber cover. Together they form a fully enclosed intake that pulls ambient ram-air into the inlet and feeds it beneath the S-FLO’s carbon cover.
Key Benefits
By keeping the incoming charge sealed off from hot engine bay air, the enclosed design keeps intake temperatures down compared to an open-element configuration that’s exposed to engine heat. Cooler, denser air feeding through the S-FLO translates into impressive power gains, all while the durable silicone construction and 4-ply reinforced tube stand up to the demands of the 4.2 V8.
Because no tune is required and AWE Tuning backs the system with a No CEL Guarantee, installation is straightforward and worry-free. Everything needed to fit the intake is in the box, so you can go from factory airbox to a fully enclosed cold air intake in one session.
