BMW M340i Performance Air Intake - Dinan - Cold Air Intake G2x/G4x Mx40i PEX - '20-'26. A semi-open system that boosts airflow and brings out genuine turbo sound for your B58 M340i.
The Dinan PEX intake reworks the lower air box, increasing volume by 60% and housing a custom 115 in² filter (40% larger than stock). Patterned secondary inlets on the cool side add volume without raising turbo inlet temps in Dinan testing. Expect up to 58% more flow, sharper throttle response, and verified gains of up to +9 WHP and +8 lb-ft on a stock car. High heat deflection PEX with OEM-like fitment; works with or without factory bracing.
