Building on the success of our well-loved intake for the BMW N55 engine, we’re excited to introduce the next generation of 6-cylinder intake systems. This upgrade takes the factory design and gives it a thoughtful boost by increasing airflow through a larger air box and filter element. The result? Improved throttle response and reduced strain on the turbocharger, leading to maximum efficiency.
While the size and redesign of the box and filter play a significant role in creating a more powerful intake, they’re not the only aspects we focused on. The magic truly lies in the details, and that’s where Dinan shines. Our engineers maintained the standard practice of using a sealed system to ensure that as much cool, outside air as possible is utilized. They also turned their attention to the intake pipe, identifying several areas for improvement.
In its factory setup, the intake tube includes baffling and a small Helmholtz chamber that help reduce unwanted noise. However, these features can create turbulence in the airflow, which ultimately takes away from the factory system’s potential power. To align with our customers' desires, we knew it was essential to remove these elements. After many iterations, we developed a carbon fiber intake tube that eliminates flow disruptions and allows the natural sound of an unobstructed intake to resonate beautifully.
This meticulous design approach means that the Dinan carbon fiber cold air intake for the B58 engine can achieve gains of 15 HP and 13 lb-ft of torque at 6000 RPM on a completely stock vehicle—an impressive accomplishment for today’s turbocharged engines.
But we didn’t stop at performance. The B58 intake is crafted entirely from carbon fiber, unlike previous 6-cylinder intakes that used a mix of materials. Not only does this intake look fantastic, but we’ve also enhanced the quality of the material compared to earlier generations. While aesthetics are important, we’ve ensured that the Dinan intake maintains its stunning appearance over time, keeping your engine bay looking sharp.
Designed to impress, perform, and endure, the Dinan B58 carbon fiber cold air intake is a must-have for any high-performance build.
