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 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. 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.

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.

Easy to install, fits larger PCs, looks great!

Simple, sturdy and looks great! This is exactly what I was looking for that actually fit my very large PC case. Works well with an UpLift standing desk.

This is a solid piece of kit. Very sturdy pieces of steel,
Color: Black, Size: Width up to 13.4''
Many options for configuration, the only thing is double check your measurements. Mine ended up just not deep enough to use it with the current desk. I have. Waiting for an updated desktop. With a sit stand desk. The bar across the middle cuts your distance in half and the purpose of buying this is because you got a big computer. Double check your measurements

Decent budget option, difficult to adjust once set up
Color: Black, Size: Width up to 13.4''
Not bad and serves it's purpose. There are better options for a few more bucks, but this one is holding very well for the price.

IT HOLDS!
Color: Black, Size: Width up to 13.4''
Heavy duty set. My desktop weighs about 60lbs, and I’m surprised how well it’s being held. I’ve always had my desktop on top of my desk. But it feels so much more roomier not having it on top of my desk. On top of that during this cold weather it’s like having a heater under my desk. Of course my desktop is gaming wise. But if you are someone with just a standard browsing desktop then it shouldn’t be hot down there. Make sure your desk is real wood or thick metal. If it’s an ikea table and the basic kind where it looks like wood, but it’s actually cardboard inside then for sure it’s gonna snap off, and that wouldn’t be pc mounts problem, rather a desk type issue.
