The Eventuri Carbon Intake for the BMW E39 M5 is a complete replacement for the stock airbox system, developed to work with the stock ECU map and MAF sensors. The stock airboxes draw air from behind the front bumper via a long flow path, with the cuboid shape creating turbulence at the transition to the circular MAF tubes. Eventuri's patented Venturi housings replace the airboxes and transition more efficiently to the MAF tubes, maintaining laminar flow.
Cold air is supplied via replacement foglamp surrounds with integrated ducts, which force ambient air through flexible neoprene ducting tubes directly to the intakes when the car is in motion, preventing heat soak. Independently dyno tested on a standard car with standard map and exhaust, with all runs carried out back-to-back on the same day with the bonnet closed.
