IE Turbo Inlet Pipe for B9/B9.5 S4 & S5 3.0T

Details Upgrading our Audi 3.0L turbocharged engine with aftermarket upgrades such as ECU tunes and larger turbos adds fast and easy power, but demands more airflow in return. The factory airbox and turbo inlet are adequate enough for stock power output, but become a large restriction on engines with aftermarket upgrades that can restrict horsepower. Pairing an IE Cast Turbo Inlet Pipe to your IE Cold Air Intake completely removes the factory flow restriction allowing your stock or aftermarket turbocharger to breathe free and make unrestricted power!LEADING FEATURESIE's inlet design has been engineered as the ultimate turbo inlet solution. Only the best materials and design features were used for a high-end fit, function, and ultimate reliability.   23% higher flow over stock turbo inlet 37.4% higher flow than stock with IE carbon intake (stock turbo) 61.49% higher flow than stock with IE intake (hybrid turbo) 4" effective inner diameter cross-section 85mm inlet side to 66mm turbo
