Forge Motorsport Carbon Induction Kit for BMW B58 (M240i, M340i, M440i)

If you already have our inlet hose and wish to purchase just the carbon intake, please see our FMINDK50-CARBON This product is a direct replacement for OEM part numbers 13718601678, 13718605164, 13718601682. The B58 engine is a masterpiece from BMW, it makes great power, produces a fantastic noise and with the addition of FMINDK50 you can take these qualities even further. When our development team analysed the OEM airbox and inlet tract on the BMW M140i kindly loaned to us from The Performance Company, we came up with a multiple part solution to maximise all areas. The Inlet Hose The sound resonator and accordion ribs on the OEM inlet hose cause significant turbulence to the airflow causing a detriment to the engine’s potential performance. Our improved solution, FMINLH25 (included in this kit), gives you a host of performance upgrades, including: Improved induction noise.

Fits: BMW M340i (G20), M440i (G22). Confirm your exact car with us before ordering.
