Dinan Cold Air Intake BMW M340i (G20) / M240i (G42) Carbon Fibre

Dinan Cold Air Intake – BMW M340i (G20) / M240i (G42) – Carbon Fibre

Dinan has been extracting power from BMW engines for decades, and this carbon fibre cold air intake is a straightforward bolt-on upgrade that makes a genuine difference. Designed to replace the restrictive factory closed-box airbox on the BMW M340i and M240i, it opens up the breathing on the B58 engine and delivers measurable power and torque gains without touching the tune.

This listing covers the G20 BMW M340i (2020–2026) and the G42 BMW M240i (2022–2026). The intake is finished in carbon fibre and replaces the factory airbox with a semi-open design that flows significantly better.

• Gains of up to 9 WHP at 6,500 RPM on a completely stock vehicle
