Carbon Fiber Intake Pipe

This upgrade replaces the factory's weak and failure-prone plastic inlet with a more durable carbon fiber construction, featuring CNC machined fittings for precise OEM fitment. By removing restrictive features and resonators found in the stock pipe, this Dinan inlet optimizes airflow, allowing the turbo to operate more efficiently and providing an amplified induction sound. This performance inlet pipe is specifically designed for BMW B58 and B46 3.0L engines. It is compatible with a wide range of BMW models including the M340i, M340i xDrive, X3 M40i, X4 M40i, M440i, M440i xDrive, M240i xDrive, and M440i Gran Coupe, as well as the Toyota GR Supra (A90/A91). Specific model years covered include 2020-2024 for many M340i and M440i variants, and 2020-2025 for X3/X4 M40i models. Pre-LCI 2018-2019 models used a different configuration and are not compatible. It is important to note that for LCI X3/X4 M40i owners seeking maximum sound, the associated Inlet Fit Kit (D763-0101) is required, as the Dinan Turbo Inlet will not mate to Dinan or factory intake systems without it.
