Karbonius Composites Race Carbon Inlet Plenum for E9X BMW M3
Karbonius Composites developed a complete carbon fiber intake system for the S65 addressing the absence of an OEM carbon plenum akin to the S54 CSL air box to enhance engine efficiency, acoustic character, and under-hood presentation. The exclusive S65 Carbon Race Plenum is engineered using advanced 3D and 2D analysis to optimize inlet airflow while reducing turbulence within the air box, contributing to measurable power gains. Beyond performance, the system delivers a distinctive motorsport aesthetic and an evocative induction sound.
