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 the Forge development team analysed the OEM airbox and inlet tract on the BMW M140i kindly loaned to them from The Performance Company, they came up with a multiple part solution to maximise all areas.
The Development Journey
Step 1: UK and some EU spec M140i’s have a blank which stops the low-pressure zone that builds up in front of the radiator from entering the inlet tract. They created FMINLD2, a carbon fibre sculped duct to replace the blank, and route more air into the tract towards the airbox.
Step 2: Now that this greater quantity of air has entered the airbox, forge need a greater surface area of filtration to maximise the airflow towards the engine. Therefore, they decided on a high-flow performance cone filter and used our development of other upper airbox induction kits to inform our design process to create FMINDK50.
Step 3: The weak link was now the OEM inlet hose with its sound resonator and accordion ribs which cause turbulence and slows down the airflow. We created FMINNLH25 (included with this kit) from a multi-ply smooth silicone to significantly reduce turbulent airflow, and to handle big boost builds. We also increased its diameter from 85mm to 90mm.
