The APR CI100038-C Cast Aluminum Turbo Inlet is designed for DIY enthusiasts adapting the APR inlet system to other intake configurations. This massive 4-inch turbo inlet is engineered to improve airflow to the turbocharger, helping support increased horsepower and torque, sharper throttle response, and enhanced engine sound. It is intended for the 2.5T TFSI engine in the 2017-2020 Audi RS3 and 2018-2022 Audi TT RS Quattro, including MK3 applications.
This APR turbo inlet is not a direct-fit replacement. Installation requires the APR Turbo Inlet Pipe, part number CI100038-B, and is designed for use with the APR Carbon Fiber Back Tube. Adapting the inlet to other intake systems may also require specialized couplers. Interchangeable adapter rings allow compatibility with various turbocharger configurations, providing added flexibility for custom intake setups.
A heat shield is included to help protect the inlet and surrounding components from excessive engine-bay temperatures. With its cast aluminum construction and high-flow design, the APR CI100038-C provides substantial airflow gains while supporting the performance goals of modified Audi RS3 and TT RS Quattro vehicles. Professional installation or careful verification of intake and turbocharger compatibility is recommended before purchase.
