The Eventuri BMW E9X M3 (S65) Black Carbon Intake System Gloss is a precision-engineered airflow upgrade developed to enhance the performance and induction character of BMW M’s legendary naturally aspirated V8. Designed specifically for the high-revving 4.0L S65 engine, this system improves the factory intake architecture while preserving the balance, drivability, and throttle response that define the E9X M3.
Although BMW’s factory airbox is highly effective, Eventuri identified airflow restrictions downstream that limit breathing efficiency, particularly at higher engine speeds where the S65 delivers its greatest performance. The system replaces the restrictive factory intake tube with a sculpted prepreg carbon fiber intake tube engineered to improve airflow velocity, reduce pressure loss, and provide a smoother transition into the factory airbox.
To further optimize performance, the intake incorporates a dedicated carbon fiber inlet scoop that increases the volume of ambient air entering the airbox. By supplying a greater volume of cooler outside air, the system helps reduce intake air temperatures while supporting more consistent power delivery during spirited driving and track use.
Rather than focusing solely on peak horsepower numbers, Eventuri engineered the intake as a complete solution that improves airflow efficiency throughout the operating range. The result is measurable horsepower and torque gains, sharper throttle response, enhanced induction sound, and improved acceleration while maintaining OEM-level refinement.
Constructed from premium prepreg carbon fiber and paired with precision-engineered supporting components, the gloss finish provides an OEM-plus engine bay appearance worthy of BMW’s final naturally aspirated V8 M engine.
