Description
Following in the footsteps of the immensely popular intake for the BMW N55 engine, the next generation of the 6-cylinder intake continues the path to success. Dinan's carbon fiber cold air intake for the B58 engine enhances the factory design by increasing airflow with a larger airbox and filter element. This improvement boosts throttle response and reduces strain on the turbocharger for maximum efficiency.
The redesign of the airbox and filter is crucial, but Dinan's attention to detail makes the difference. By maintaining a sealed system to ensure the use of as much cold outside air as possible, Dinan engineers also focused on the intake pipe. The factory intake tube includes baffling and a small Helmholtz chamber to reduce unwanted sound, but these features create a turbulent airflow that robs potential power. Dinan's carbon fiber intake tube eliminates these disruptions, allowing the natural sound of an unimpeded intake tract to resonate.
The Dinan carbon fiber cold air intake for the B58 engine delivers gains of 15 HP and 13 lb-ft of torque at 6000 RPM on a completely stock vehicle—an impressive feat for modern turbocharged engines.
Key Features:
- More Power: +15 HP and +13 lb-ft of torque at 6000 RPM (+13 WHP and +11 WTQ) without additional modifications
- Sportier Sound: Unimpeded intake tract delivers a natural, aggressive engine note
