Not to be outdone by the performance side of the equation, the B46/B48 intake also is completely made up of carbon fiber unlike 4-cylinder 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 B46/B48 carbon fiber intake is a modification that is a must for any enthusiast that places sound atop their requirements list.
