    Description

    Following in the footsteps of the immensely popular and heralded intake for the BMW N55 engine, the next generation of 6 cylinder intake takes the same path to success. 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 major factors 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. Coupled with maintaining Dinan's standard practice of utilizing a sealed system to ensure as much cold outside air as possible is employed 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 that robs the factory system of potential power. These 2 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 cold air intake for the B58 engine to elicit gains of 15 HP and 13 TRQ 6000 RPM on a completely stock vehicle. An impressive feat on today's turbocharged engines.
