DINAN B58 Carbon Fibre Turbo Inlet Pipe - BMW M240i/M340i/M440i/Z4 M40i & Toyota GR Supra 3.0 (20-24)

DINAN B58 Carbon Fibre Turbo Inlet Pipe – BMW M240i / M340i / M440i / Z4 M40i & Toyota GR Supra 3.0 (2020–2024)

The DINAN B58 Carbon Fibre Turbo Inlet Pipe is engineered to optimise airflow and turbo efficiency while delivering an enhanced induction soundtrack. By replacing the restrictive factory plastic inlet with a robust, lightweight carbon fibre assembly, Dinan increases airflow volume, reduces turbulence, and eliminates the built-in sound resonator — unlocking both measurable performance gains and a more aggressive turbo sound.

Constructed with CNC-machined fittings for perfect OEM fitment, this upgraded inlet maximises flow and durability while maintaining a clean, factory-style installation. The result is improved turbo response, better efficiency, and a sharper, more visceral driving experience.
