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.
Multi ply silicone construction improves longevity of FMINLH25 over that of the OEM hose.
5 ply silicone construction will be able to handle strain of engine mapping far better than OEM hose.
Increase of diameter at airbox end from 85mm to 90mm.
