While sound is undoubtedly important for a large swath of consumers, performance enhancements are equally as important to others. Common to all Dinan intake design, improvements upon the factory design by increasing flow via a larger airbox and filter element were made. These standard adjustments improve throttle response (and acceleration) and lessen the strain on the turbocharger for maximum efficiency. While box and filter enlargement and redesign are major factors in ultimately producing a more potent intake, they are not the only variables in creating a more efficient design either. The resonator assembly that limited auditory enjoyment also created a more turbulent airflow path by introducing alternative stunted pathways. The Dinan carbon fiber intake tube eliminates these flow disruptions with a smoother, direct flow path for maximum potential efficiency and an overall 7% increase in flow when compared to stock.
