Introducing our highly anticipated S85 Carbon Fiber Plenum – a masterpiece crafted from 100% premium prepreg carbon fiber, right down to the internal trumpets. This plenum serves as a seamless replacement for the OEM plastic variant.

It was designed with a singular purpose: to elevate the induction sound while preserving the performance and drivability that BMW intended. We’ve maintained the precise internal volume and trumpet lengths meticulously tuned by BMW engineers. By adhering to these specifications, we ensure no compromise in power delivery, safeguarding your low-end torque.

While the carbon plenum doesn’t provide a performance boost per se, it’s the symphony of induction sounds it orchestrates that truly transforms the driving experience of the E6X M5/M6.

This plenum can be used with the OEM airboxes or any aftermarket intake system. Our own additional E60 M5 and E63 / E64 M6 intake system provides a genuine performance gain and can be found HERE.

NOTE: The ///M and V10 Emblems are optional; installed photos show carbon intake system available separately
