APR Forged Carbon Fiber Intake System - Audi SQ7 / SQ8 / RS Q8 4.0T 2019-2027

Built for the 4.0T EA825 V8, this system swaps the small split-body factory plenum for a single-piece matte forged carbon fiber plenum that runs past integrated billet aluminum PCV and EVAP bungs and down to new billet aluminum turbocharger inlets with bell mouth profiles. The larger cross section and smoother path raise system flow by up to 22% over stock and cut pressure drop, and the high-flow cotton gauze filter adds up to 12% more flow than the factory element while staying washable and reusable. New EVAP jet pumps are included, and the high-flow inlets leave room to move to larger turbochargers later.
