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 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.

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 vehicle.

The Carbon Fibre


Using carbon fibre brings obvious benefits of strength, lightweight and aesthetics. However, a part that is often forgotten is its low thermal conductivity, which means it reduces heat soak and transmission of said heat to nearby items. Keeping Inlet Air Temps (IAT’s) low is often a difficult part of developing induction systems, so replacing metal or plastic inlet solutions for FMINDK50 will help decrease IAT’s and increase the volume of air supplied to your vehicles engine that is compressed by the turbo charger.

This has a better effect on performance when cool as this is to provide the engine with more oxygen (denser air), thus improving the combustion in each cylinder. In addition, by regulating and reducing the air temperature, it also increases the reliability of an engine by keeping the AFRs (Air Fuel Ratios) in each cylinder at a safe level, which in turn, can increase an engines power due to the air being cooler. A bigger bang is then created within the cylinder, providing the correct amount of fuel is added. This can equate to an increase in BHP and torque.


Testing

 

Testing was completed using Performance Remap in Gloucester with their VTEC 4 wheel drive dynamometer. This was to ensure all our data has been achieved with results as accurately as possible by an independent tuner. The results below speak for themselves, also with the added benefit of being a very easy component to fit with no specialist tools this is superb, affordable modification for the BMW enthusiast.

From the Dyno Graph shown above performance gains can be expected from 2500RPM to the red line with 11BHP and around 19NM of torque at peak RPM. The torque increase is clearly visible on the dyno graph and is clear when driving the car. As soon as it comes onto boost you can feel that hit of extra torque pushing you all the way to the redline. The M140i tested on the dyno was stock other than a Pipercross performance panel filter, but with a tuned vehicle you will see greater percentage gains as the vehicle will be able to utilise the increase in volume of cold air.

FMINDK50 is part of our acclaimed Hi Flow range and will ensure that your vehicle is getting critical cold air. Not only is the Forge part a better option for performance, but the carbon fibre really helps to give the engine bay some character. The weave of the carbon has been optimised to match the carbon on the intake manifold, which really shows the level of detail we put into our designs. The high-quality carbon fibre is prepreg 2x2 twill formed in an autoclave from billet tooling and finished with an anti UV gloss gel coat. The Forge Motorsport lifetime warranty* on all hardware products shows the trust we have in the quality of our products while they are being enjoyed on your pride and joy.

The kit comes complete with everything you need for installation which can be carried out in around 1 hour, including a set of full colour instructions. For such an easy to fit product it truly does create some remarkable gains. If you are looking at whether FMINDK50 fits a vehicle not specified in our compatible vehicle listing, please check if your OEM upper airbox has a channel for the strut bar to fit through, if it does FMINDK50 will not fit your vehicle. Please contact us with a photo of your engine bay if you have any questions.

Induction Kit and Inlet Duct Package

FMINLD2 is a simple bolt-on product which is easy to fit in approximately 45 minutes with no specialist tool, drilling or cutting required. Not only is the Forge part a better option for performance, but the carbon fibre really helps to give the front of your BMW a pleasant aesthetic appearance. The high-quality composite fibre is manufactured from 100% prepreg 2x2 carbon fibre twill formed in an autoclave from billet tooling and finished with an anti UV gloss gel coat.

Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator, or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.

This warranty does not apply to any defect in the goods arising from fair wear and tear, wilful damage, accident, negligence by you or any third party, use otherwise than as recommended by the supplier, failure to follow the supplier’s instructions, or any alteration or repair carried out without the supplier’s approval.
