Performance gains / why it is needed
This plenum does not increase peak power. It preserves BMW tuned trumpet lengths and internal volume so torque and power stay stock. The real gain is acoustic. You get a richer, more engaging V8 induction sound similar to lightweight race plenums but without sacrificing drivability.
What is included in the kit
1x matte prepreg carbon plenum with integrated trumpets. All required seals and mounting brackets included unless stated otherwise.
