The Speed Engineering inlet duct kit is designed for all BMW F-Series Non-M models with an M package bumper. The Clubsport variant is intended for occasional track riders who cannot do without braking performance and at the same time prefer a plug & play and 100% retrofittable solution. For regular track use, however, it is recommend to use the track variants of this kit (e.g. available for the F20/F21).

Most F-Series models already have intake ducts in the front bumper ex works, but these end in the middle of the wheel arch. In order not to randomly swirl the air in the wheel arch, Speed Engineering have developed an extension of the air duct, which can be installed with minimal effort and guides the air around the wheel and connects the air duct to the outlet via a hose (per side).

For many vehicles brake cooling is recommended even under medium-heavy loads, even off the race track. This not only improves braking performance, but also drastically reduces wear on the brake pads and discs.

The Speed Engineering anchor plate uses the channelling of airflow to the centre of the brake disc to use the turbine effect to cool the disc from the inside. In doing so, the disc is targeted at a defined angle so as not to suffer any wastage and to use the available air volume as efficiently as possible. Due to the light construction in combination with powdered aluminium, the anchor plate is sufficiently strong and at the same time light and insensitive.

The different models vary slightly in the wheel position, coupled with different chassis geometries and wheel and tyre combinations, it is impossible for all variants to be covered. In the worst case, the wheel could hit the ducting when the steering wheel is fully turned (which should only be the case when parking), which cannot damage the tyre. In this case we would ask you to do without the last ¼ of the steering turns.

The required brake hose diameter is 51mm (1m included).
