This product is a direct replacement for OEM part numbers 13718601678, 13718605164, 13718601682.
When our development team analysed the OEM airbox and inlet tract on the BMW M140i kindly loaned to us from The Performance Company, we could see some obvious gains that could be had across the platform. As such we wasted no time in comparing the B58 powered M140i with a B48 powered BMW 230i and were able to locate some useful similarities between the two. Therefore, we came up with a multiple part solution to maximise all areas.
The Development Journey
Step 1: UK and some EU spec F chassis BMW’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 FMINDK55.
Step 3:The weak link was now the OEM inlet hose with its sound resonator and accordion ribs which cause turbulence and slow down the airflow. We created a multi-ply smooth silicone to significantly reduce turbulent airflow, and to handle tuned vehicles with ease.
We used SolidWorks CAD, 3D prints and numerous dyno sessions to truly unlock the power. Simulation testing played a large part in the design process to help maximise the airflow.
We were able to experiment with the airflow entering the chamber from the inlet tract into the lower airbox, by changing the position of the filter, the size and location of the louvres and other variables to ensure that the intake is maximising performance.
The 3D printed prototypes helped with comparing our simulation testing to real world driving conditions.
Please see our video on YouTube which shows dyno testing of our final prototype. This is a valuable comparison that is used in the top tiers of motorsport, now being brought to your
