Prepreg 2×2 twill formed carbon fibre

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. We 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, we need a greater surface area of filtration to maximise the airflow towards the engine. Therefore, we 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 FMINLH25 (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.
