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 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.

Durable and Rugged
Color: Black
I've had it for a few weeks now. It was a replacement I bought after buying several vinyl type covers. This one is a good gauge of plastic and rubber. The rubber seems pretty strong and it protects the iPad well on the corners and back. The back is mostly covered except for the Apple logo in the center. In addition to protecting the corners and also protects the camera lens as the rubber after insulation is a little bit higher than the lens so when you put this down, it's not going to scratch the lens. It has a pen slot, which I like and plenty of room to grip the device if I'm carrying it from place a place or when I'm using it, I can grip the edge and not touch the screen. One of the things I would've liked included is a screen protector, but nothing covers the screen. I also miss the folio type cover because the screen will gather dust now. But, Apple screens are fairly durable so I'm not too worried about breaking it. It was easy to install. It came in as it came in a couple of pieces that you just pressed together. All the controls are obvious as they are under the rubber, but they look like keys. One more thing I might bring up is the charging port. It's easy to get to even though it's a little deep. On my iPad the touch sensor is on the on off button and it is a little harder to do than if I didn't have any case on it, but that is to be expected. It also has an easel that unfolds from the back if you want to sit it up, but I don't use it for watching anything since I have a real TV set. So far I like it and I'm glad I bought this as I don't think it's going to wear out as quickly from me handling it as the others did. The value was good as long as it lasts.

Not broken yet.

I bought this for my daughter’s tablet and she has put it through the test. It has been dropped multiple times and the tablets still good. It was easy to put on, looks good, and does the job.
