BMW X4 M40i Performance Air Intake - Dinan - Carbon Fiber, Cold Air (2020–2025). A precision-engineered upgrade for the G02 LCI X4 M40i that improves airflow and adds refined induction sound with factory-like fitment.
Dinan reimagines the stock system with a 66% larger air box and a 44% larger filter area to reduce restriction and turbo effort for sharper throttle response. The optimized carbon fiber intake tube removes the factory resonator and straightens the flow path, while a semi-open lid with tuned sound ports brings out the turbo’s character. The high-flow cotton gauze filter is washable and reusable. Fits 2020–2025 X4 M40i (LCI only); not compatible with 2018–2019 pre-LCI models. For additional sound, the Dinan Turbo Inlet (D760-0062) may be paired with the required Fit Kit (D763-0101). Airflow is approximately 7% higher than stock.
