High-Flow Intake Kit

The CTS Turbo High-Flow Intake Kit is meticulously engineered to replace the restrictive factory airbox system on the BMW S63 4.4L twin-turbo engine, found in the F10/F12/F13 M5 and M6 models. The primary design goal was to develop the largest, loudest, and highest-flowing intake available, transforming the sound of your twin-turbo V8 to match its performance potential. The kit features smooth 3″ aluminum intake pipes that ensure a perfect connection to the turbo inlets. The system is finished with a black powder coat for an OEM appearance. Included are two sets of couplers, catering to both Competition and standard model fitments, ensuring broad compatibility within the specified vehicle range. Installation of this intake system is designed to yield immediate improvements, with peak power gains ranging from 12 to 20HP, depending on fuel quality and elevation, without requiring any additional tuning. Beyond the power increase, the system delivers an aggressive, race-inspired sound and an enhanced torque curve across the entire power band.
