The HARD Motorsport Brake Cooling DUCT kit is designed for maximum efficiency specifically for the BMW E46. The Low Profile design allows for more clearance for greater turning radius. An aluminum plate on the exterior side adds even more protection against wear from tire contact. No more destroying expensive flex hose.

Race inspired by modern duct design of top motorsport teams and manufacturers.

Easy Mounting:

Ducts include a sturdy aluminum mounting bracket that utilizes existing hardware. No drilling needed.

Track and Daily Driver Compatible :

Our low-profile ducts were CAD designed from laser scans of the E46 chassis to be compatible with OEM A/C Equipment. The forward splash guard will need to be modified or removed (as pictured) to allow for installation of the duct kit.
