Dinan Carbon Fiber Turbo Inlet Pipe - BMW M340i / Toyota GR Supra 2020-2026

The Dinan turbo inlet pipe swaps the weak plastic factory inlet for a robust carbon fiber pipe with CNC-machined fittings, installing as a direct OEM-style replacement. Eliminating the factory resonators and optimizing the path delivers an average 7.7% larger internal diameter and 14% more internal volume for smoother, less turbulent airflow. The result is a more efficient turbo and an enhanced induction sound.
