Air Duct Inlet
In order to transport the air to the outlet of the brake ventilation, a suitable inlet is essential. Some E46 3 Series already has intake ducts in the front bumper from factory, but these are 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, which guides the air around the wheel and connects the air duct to our anchor plate via a 40 cm long hose (per side).
Air Duct Outlet
Here, too, the brake disc must be flowed with air as centrally as possible. The brake disc of the E46 3 Series does not offer a very large pot. A classic solution using an anchor plate would therefore result in the inner surface of the friction disc being cooled on one side. However, in order to use the turbine effect of the brake disc, Speed Engineering have developed a brake cooling system, which is mounted on the wishbone and flows to the centre of the disc regardless of the wheel position. It is simply attached using existing locking pins and without permanent changes to the vehicle.
Important Information
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).
Suitable for E46 3 Series models if an OEM air duct is already present.
