Dinan Semi-Open Carbon Fiber Cold Air Intake for BMW 430i 2017-2018

Beyond the additional sound opening the semi-open intake takes the same path to success as its closed box counterpart. Improve upon the factory design by increasing flow via a larger airbox and filter element thereby improving throttle response and lessening the strain on the turbocharger for maximum efficiency. While box and filter enlargement and redesign are a major factor in ultimately producing a more potent intake, they are not the only variables in creating a more efficient design either. The devil is in the details which is where Dinan thrives. Dinan engineers focused their attention on the intake pipe itself where numerous improvements could be made. In factory configuration, the intake tube comes complete with baffling and a small Helmholtz chamber to reduce unwanted sound. As a byproduct, these features also cause a more turbulent airflow path which robs the factory system of potential power. These two specific details are diametrically opposed to our intended market's desires, so the removal of these features was paramount. Through numerous iterations, a carbon fiber intake tube was developed that eliminated flow disruptions and allowed the natural sound of an unimpeded intake tract to sing. All told this thorough methodology of design allows the Dinan carbon fiber intake for the B46/B48 engine to elicit gains of 6 HP and 6 TRQ at 5000 RPM on a completely stock vehicle. Semi-Open - Carbon Fiber - F22/F23/F30/F31/F32/F33/F34/F36 For those who already own a closed box Dinan intake (D760-0048) but now want to switch to the semi-open intake without purchasing a completely new kit, you can order the retrofit kit (lid only) seperately for $179.95. To do so contact the tech sales department at 1-800-341-5480 and request part number D763-0213-G-A.
