FORGE FMINDK12 BMW M3/M4 Carbon Fibre Induction Kit

A completely standard vehicle was sourced for the final dyno testing.

The Forge High Flow airbox produced an impressive 12bhp and 20ftlb increase on independent dyno testing

Forge Motorsport are proud to present the latest in their “Hi Flow” performance range the Carbon intake for the for the BMW M4

The carbon fibre parts were created from a mould that was hand finished and refined by one of our many skilled craftsmen at Forge Motorsport HQ in Gloucestershire, England. We then utilised our Solid works CAD design system to assist in the creation, modification, analysis and optimization of the High Flow range.

The Forge Carbon air intake has been designed to improve the engines ability to breathe and to increase performance. Our engineers have looked at every characteristic and made improvements in volume, shape, size of intake and airbox construction, this has all been maximised to contribute in achieving optimum performance and allow the engine to draw in as much air as possible.

The airbox comes manufactured in an autoclave using prepreg carbon fibre, by using this technology on Forge Carbon fibre parts we have made a product that is much lighter and (20-40%) stronger than liquid infusion.

With this unique sleek design, you can expect to see a carbon fibre housing that flows beautifully along the engine bay, giving you more horse power and torque, and hopefully an appreciation for the care and time that has gone into the production.

Having spent so much time on the carbon development we then turned to the equally important aspect of filtration. We engaged our partners and experts in Filtration Control, Pipercross.

With over 25 years’ experience in both the domestic and motorsport market they recommended a multi-layer foam construction filter, these filters work perfectly in our ‘Hi-Flow’ range. The two large filters provided, flows 30% more air than the stock filter and fits snuggly within the housing.

Please note - the Pipercross filter is excluded from the Forge lifetime warranty

Please watch our video on how to fit an air filter without damaging it.

DO NOT OVER TIGHTENWhen fitting the filter to its counterpart please ensure you do not over tighten the hose clamp connecting them. Doing so could result in the part being crushed, leading to fitment and/or performance issues. The recommended torque setting for this hose clamp is 2-2.4Nm
