Carbon Fiber Semi-Open Intake

The Dinan Carbon Fiber Semi-Open Intake is engineered to deliver enhanced performance and a more aggressive auditory experience for your BMW F22/23 and F3X models equipped with the B46 or B48 2.0L engine. This intake system aims to improve upon the factory design by significantly increasing airflow through a larger airbox and filter element. This results in better throttle response and reduces the strain on the turbocharger, leading to increased overall efficiency. Constructed entirely from carbon fiber, this intake features an optimized intake tube that removes factory baffling and Helmholtz chambers. These elements in the stock system create turbulent airflow, which hinders performance. By eliminating them, Dinan ensures a smoother, unimpeded flow path, allowing the natural sound of the engine and turbocharger to be more pronounced and enjoyable. The airbox is 30% larger than stock, and the filter area is increased by 34% for maximum airflow. This Dinan intake system provides a claimed power increase of 6 HP and 6 lb-ft of torque at 5000 RPM. It is designed for quick and easy installation and is 50 State Emissions Legal, specifically for 2019-2021 F2x/F3x 230i/330i/430i models (CARB EO D-176-56). The product is backed by Dinan's Lifetime Replacement Program.
