In order to transport the air to the outlet of the brake ventilation, a suitable inlet is essential. The G8x M3/M4 already has intake ducts in the front bumper ex works, but these end in the middle of the wheel housing. In order not to randomly swirl the air in the wheel housing, Speed Engineering have developed an extension of the air duct, which can be installed with minimal effort and connects the air to the outlet using a hose around the wheel. No fastening tool is required for assembly. It is exchanged with the original duct socket. The channel is based on the OEM channel and therefore uses exactly the same connection points and can therefore be retrofitted 100% without leaving any residue.

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 (not included). The matching brake hose and hose clamps are optionally available to order. A complete front brake cooling kit for the G8x M3/M4 is also available here.

Suitable for all G80 M3 Sedan, G82 M4 Coupe and G83 M4 Convertible (Rear Wheel Drive and M xDrive) models.
