BMW E39 M5

The BMW E39 M5 Eventuri intake is designed to offer a complete solution as an upgrade to the stock airbox system. Our aim was to develop an intake system for the S62 engine which worked with the stock ECU map and MAF sensors and produced a genuine improvement in the driving experience. With Our Patent Pending Venturi housing, we have ensured that the airflow remains as laminar as possible. Furthermore, the addition of a true cold air feed by adding scoops integrated with the front fog lamps results in the lowest possible inlet air temperature. This leads to an optimized intake system that delivers noticeable performance gains consistently.
Performance Gain: 8-12hp, 8-10ft-lb

The Eventuri Difference

The E39 M5 Eventuri system uses our Patent Pending Carbon fiber Housings with our bespoke Gen-2 filter which provides an aerodynamically efficient airflow path from the filter to the inlet tubes. Not just another cone filter with a heat shield but a unique design that invokes the Venturi effect.

The Eventuri E39 M5 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. Here are the details for each component and the design ethos behind them:

Each intake system consists of:

2 Carbon Fibre Venturi housings

2 High Flow generation 2 Air Filters

2 Aluminium Cowls for smooth airflow entry

2 Foglamp surrounds with integrated air ducts

2 Flexible Neoprene air ducting sections

2 Laser Cut Aluminium Shields

Laser Cut Custom Brackets

High-quality Silicon couplers with BMW specification hose clamps

Carbon Intake Housing Assemblies

The filter housings comprise of the high flow filters, aluminum cowls and the carbon pods themselves. The carbon pods shroud the reverse mounted filter and smoothly shape the airflow down to the MAF tubes. This smooth reduction in cross-sectional area invokes the Venturi effect where the airflow accelerates whilst maintaining laminar conditions. It can be thought of as a large velocity stack – below is a diagram to show the comparison between our patent pending design and a regular intake system. Our bespoke filters aid the airflow moving through the housings and allow for an even velocity profile as the airflow exits the housings. Further details can be read in the Technology and Filters pages.

Foglamp Ducts

To supply the intakes with cold air we designed replacement Foglamp surrounds with integrated ducts. The area for cold air entry has been maximised for the given shape and size of the surround and the duct transitions to the supplied flexible neoprene ducting tubes. While the car is in motion, ambient air is forced into these ducts which are connected to the neoprene tubes to transfer the airflow directly to the intakes. This ensures that the intakes do not get heat soaked and the engine is able to draw air at ambient temperatures.
