Dinan Cold Air Intake for BMW M340i (G20) / M240i (G42) | D760-0052

Unleash hidden performance and elevate the aesthetics of your BMW M340i or M240i with the Dinan Carbon Fiber Cold Air Intake System (D760-0052)—designed to deliver more power, better response, and a bold under-hood presence that matches the aggressive character of your B58-powered BMW.

The factory airbox on these models does its job quietly and conservatively—but Dinan is here to change that. With a 58% increase in airflow and a stunning carbon fiber construction, this semi-open intake system provides real-world performance gains and a soundtrack that enthusiasts crave.
