The Quick and Dirty:

  • More Power: + 15 HP @ 6000 RPM & + 13 lb-ft @ 6000 RPM (+ 13 WHP & + 11 WTQ) without additional modifications for the B58 engine
  • More Power: + 6 HP @ 5000 RPM & + 6 lb-ft @ 5000 RPM (+ 5 WHP & + 5 WTQ) without additional modifications for the B46/B48 engines.
  • A pronounced sporty sound courtesy of a semi-open design
  • Improved throttle response
  • Larger volume air box (30% larger than stock) for increased breathability
  • 34% increase in filter area (stock: 76.3in², Dinan: 102.1in²) for optimum flow
  • Optimized carbon fiber intake tube
  • Free flowing injection molded Air Mass Meter housing (8-20% larger than stock)
  • Quick and easy installation

The Story:

Looking for more sound than what can be attained from the standard Dinan closed box intake on F2x/F3x B58/B48/B46 powered vehicles but don’t want to sacrifice all the performance gains or the beautifully crafted carbon fiber design in the process? This semi-open variant of the same intake meets those demands using a revised lid with an additional auditory port so those intoxicating turbo noises can be more easily heard.

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, carbon fiber intake tubes were 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 either the B58 or B46/B48 engine to elicit moderate gains on a completely stock vehicle.

Not to be outdone by the performance side of the equation, the intakes are also completely made up of carbon fiber unlike intakes of previous generations where a mix of materials were used. Not only is the intake completely carbon construction but the quality of the material has been improved as well. While looks are surely important, and this piece has that department covered in spades, the improved construction and coating also guarantees that the appearance of the engine bay with the Dinan intake will not be marred over time. Built to elicit a more pronounced sound, imbue the engine bay with some carbon class, perform, and last the duration-- the Dinan semi-open carbon fiber intakes are a modification that is a must for any enthusiast that places sound atop their requirements list.
