Unitronic 4 inch Turbo Inlet Elbow for 2.5TFSI EVO

If you're looking to maximize airflow on your EA855 EVO-powered Audi RS3 or TT RS, the Unitronic 4" Turbo Inlet Elbow is one of the most effective supporting modifications available. Designed to eliminate the restrictions of the factory turbo inlet, this cast aluminum upgrade delivers a massive 28% increase in airflow over stock while maintaining proper PCV functionality and OEM-like fitment. Whether you're running the factory turbocharger or stepping into hybrid turbo territory, the Unitronic 4" Turbo Inlet Elbow is engineered to support the airflow demands of higher horsepower builds. Using advanced 3D scanning and CAD modeling, Unitronic developed a true bolt-on solution that integrates seamlessly with aftermarket intake systems while retaining factory mounting locations. Modular billet aluminum adapter rings allow compatibility with many of today's most popular hybrid turbocharger options, making this inlet a smart investment whether you're Stage 1 today or planning bigger things tomorrow.

For stock turbo cars, this is one of those supporting mods that helps the entire intake tract breathe easier. For hybrid turbo cars, it becomes even more important. What we like about the Unitronic design is that they didn't just make it bigger—they engineered it correctly. Proper PCV integration, quality casting, excellent fitment, and adapter options for future turbo upgrades make this one of those "buy it once" parts that can grow with your build. NOTE: This product is compatible with Left Hand Drive (LHD) models only. Does not work with stock intake.
