BMW Z4M E85 / E86. The Z4M intake follows on from our E46 M3 system as a result of extensive data logging, dyno testing and design optimisation. Our aim was to develop an intake system for the S54 engine which worked with the stock ECU map and MAF sensor and produced a genuine improvement in the driving experience. The Z4M Eventuri system uses our Patent Pending carbon fibre housing which provides an aerodynamically efficient airflow path from the filter to the MAF tube. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect.The item "Eventuri Carbon Fibre Air Intake Kit fits BMW Z4M E85 / E86" is in sale since Friday, November 30, 2018.
