Carbon Fiber Black Intake. Performance Gain: 8-12hp, 8-10ft-lb The BMW E39 M5 Eventuri intake is built 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 optimised intake system which provides noticeable performance gains consistently. The Eventuri Difference The E39 M5 Eventuri system uses our Patent Pending Carbon fibre Housings with our bespoke Gen-2 filter which provide 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 which invokes the Venturi affect. *By request/order.
