EVENTURI Intake System. Performance Gain: 16-18hp, 20-22ft-lb. The Civic intake follows on from a result of extensive data logging, dyno testing and design optimisation. Our aim was to develop an intake system for the K20C1 engine which worked with the stock ECU map and MAF sensor and produced a genuine improvement in the driving experience. The Eventuri Difference -the 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.
