Carbon Induction Kit for BMW B58 (M240i, M340i, M440i) - Carbon Intake Only

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 Carbon Fibre

Using carbon fibre brings obvious benefits of strength, lightweight and aesthetics. However, a part that is often forgotten is its low thermal conductivity, which means it reduces heat soak and transmission of said heat to nearby items. Keeping Inlet Air Temps (IAT’s) low is often a difficult part of developing induction systems, so replacing metal or plastic inlet solutions for FMINDK50 will help decrease IAT’s and increase the volume of air supplied to your vehicles engine that is compressed by the turbo charger.

This has a better effect on performance when cool as this is to provide the engine with more oxygen (denser air), thus improving the combustion in each cylinder. In addition, by regulating and reducing the air temperature, it also increases the reliability of an engine by keeping the AFRs (Air Fuel Ratios) in each cylinder at a safe level, which in turn, can increase an engines power due to the air being cooler. A bigger bang is then created within the cylinder, providing the correct amount of fuel is added. This can equate to an increase in BHP and torque.
