High-Flow Intake Kit for BMW S63TU/N63TU 4.4L Twin-Turbo

The CTS Turbo IT-825 intake kit is engineered to provide unrestricted airflow for BMW S63TU4 and N63T3 4.4L twin-turbo engines. This complete replacement for the factory system is designed for maximum flow, featuring a large 6-inch velocity stack reusable air filter and a 3-inch smooth aluminum intake pipe that seamlessly connects to the turbo inlet. To ensure optimal performance, a turbo heat shield is included to minimize air intake temperatures. This intake system is constructed with quality materials, including aluminum for the intake pipe and black silicone couplers, and features a black powder coat finish for an OEM appearance. Without requiring any additional tuning, users can expect peak power gains ranging from 12 to 20 HP, which are dependent on fuel and elevation.
