IE Turbo Inlet Pipe Audi S4, S5 B9 3.0 TFSI
 
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!
 
IE'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.
 
We know you want the most performance from your investment in aftermarket upgrades and wouldn't sacrifice power for a small, plastic, factory-equipped turbo inlet. IE's engineers have thrown out the factory design and started from the ground up to maximize performance. Utilizing advanced engineering techniques and industry-leading manufacturing processes, IE's Turbo Inlet Pipe takes full advantage of all available space with a unique shape to maximize airflow. This optimized design results in a massive 23% increase in flow over stock!
 
IE's Turbo Inlet fits Audi B9 S4 & S5 3.0T V6 Turbocharged engines without any modifications or installation hassles. The install process is straightforward and can be done with basic tools. Fitment is not verified on non-IE brand intakes without modification, purchase is at your own risk.
