Dinan Carbon Fiber Cold Air Intake - BMW G05 / G12 / G15 540i / 740i / 840i / X5 / X6 40i

The Dinan Carbon Fiber Cold Air Intake for the B58-powered BMW 540i, 740i, 840i, X5 40i, and X6 40i enlarges the airbox and filter element while replacing the factory resonator-equipped intake tube with a carbon fiber pipe that delivers 20% greater airflow than stock. The factory resonator assembly restricts flow by introducing turbulence and alternative stunted pathways that cost the B58 turbocharger efficiency. The Dinan CF intake tube eliminates these disruptions with a smooth, direct path to the compressor inlet. Together with the enlarged airbox and filter, the system reduces turbocharger strain, improves throttle response, and produces an amplified intake character over the factory-muffled setup.
