Eventuri Carbon Fibre Intake System - BMW E39 M5

The Eventuri Carbon Fibre Intake System is a direct replacement for the stock E39 M5 airbox, engineered to improve airflow and reduce inlet temperatures. By using patent-pending Venturi housings and true cold air feeds, this system delivers noticeable performance gains while maintaining compatibility with the stock ECU and MAF sensors.

Key Features & Benefits

Performance Gains / Why It’s Needed

Stock E39 M5 airboxes draw air from behind the bumper, causing drag and turbulence. Eventuri replaces these with aerodynamic Venturi housings, smoother MAF transitions, and cooler intake air. This improves throttle response, midrange power, and overall engine efficiency on road or track.
