4-Inch Turbo Inlet Elbow

The Unitronic 4-inch Turbo Inlet Elbow provides a performance-oriented airflow solution for the 2.5TFSI EVO engine in 8Y RS3 vehicles. Designed with extensive engineering input, the elbow replaces restrictive factory piping to support both the stock turbocharger and various mainstream hybrid turbo configurations through the use of modular, CNC-machined billet aluminum adapter rings. Installation typically requires 1-2 hours and is designed as a direct-fit replacement, though users must note that this product does not work with the stock intake system. Compatibility is limited to Left Hand Drive (LHD) models only; it is not compatible with Right Hand Drive (RHD) vehicles. Additionally, for 8Y.2 RS3 fitment, the separate purchase of a Unitronic PCV adapter is required for proper installation. Given its performance focus, this part is optimized for use alongside Unitronic's aftermarket intake systems to achieve maximum flow and power gains.
