Description
Unitronic’s 4" Turbo Inlet Elbow is engineered specifically for the 8Y RS3 equipped with the 2.5TFSI EVO (DXH) engine. Drawing on extensive experience with previous 2.5TFSI EVO applications, Unitronic Mechanical Engineers designed this elbow to retain full OEM PCV functionality while improving turbo efficiency and airflow.
Constructed from aircraft-grade cast aluminum and paired with modular CNC-machined adapter rings, this turbo inlet elbow supports the airflow demands of the factory turbo as well as most mainstream hybrid turbos on the market. For maximum gains, it pairs perfectly with Unitronic’s 4" Carbon Fiber or 4" Forged Carbon Fiber Intake Systems.
