Eventuri Hybrid Carbon Airbox System - E46 M3

Experience the ultimate evolution of induction design with the Eventuri Hybrid Carbon Airbox System, engineered exclusively for the BMW E46 M3. Developed to bridge the gap between CSL performance and OEM drivability, this system unleashes the raw, high-pitched CSL intake note while retaining full MAF sensor compatibility—no ECU conversion, no tune, and zero drivability compromise. With over a year of CFD refinement and acoustic tuning, Eventuri’s Hybrid Airbox delivers CSL-level throttle response and induction resonance through a precision-molded plenum and patented Venturi filter housing. It’s the only plug-and-play intake that captures the authentic CSL sound while maintaining factory smoothness and reliability. Key Features Authentic CSL induction sound with full MAF integration — no tune required CFD-optimized airbox geometry ensures balanced airflow across all six trumpets Improved throttle response and smooth, OEM-like drivability Patented Venturi filter housing for stable, laminar airflow Prepreg carbon fiber construction — autoclave-cured for strength and heat resistance Cold air carbon scoop feeds the intake directly from the brake duct while retaining cooling flow Plug-and-play installation — no modifications, no CEL, no ECU coding Configuration Options Configuration Part Number Best For Hybrid Airbox + Full Carbon Intake EVE-E46ABX-CF-INT Owners upgrading from the factory airbox Hybrid Airbox Only, reuse Eventuri intake housing and scoop EVE-E46ABX-CF-PLM Existing Eventuri intake owners Engineering Highlights Six precision-molded glass fiber trumpets with CNC stainless reinforcement rings CNC-machined MAF boss and breather adapters Stainless brackets and gaskets ensure long-term airtight sealing Reverse-mounted dry filter for laminar flow and consistent MAF readings Cold air scoop with CNC collar integrates seamlessly in the OEM brake duct Fitment BMW E46 M3 (2001–2006) Engine: S54 Compatible with LHD and RHD models Note: This item is built for performance applications and not eligible for return. ** This item is not eligible for return **
