AAF Brake Duct Kit w/Adapter For Factory Inlet - E30

Product Details

Since 2010, Advanced Auto Fabrication has been producing and developing both parts and full fledged race cars. Their knowledge base covers a wide range of vehicles both domestic and imported. In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars.

Extend the life of your calipers pads and rotors with the AAF E30 Brake Cooling Duct Kit. Brake cooling is a must for BMW’s that see track use.

AAF's Backing Plates feature a large “Pocket” to allow for more efficient air flow into the brake hat. This allows air to travel through the vents in the rotor. AAF's Backing Plate is the full size of the rotor and is a heat shield for the shocks and ball joints.

The lightweight aluminum tubes provide a sturdy enough passage for air to travel to the rotor, while being able to take some abuse if the tire or road debris comes into contact with it.  On very tight turns the tire will contact the aluminum tube and not the flex hose making the flex hose last much longer.

The AAF adapter inlet attaches directly to the factory brake duct inlet with no other modifications needed(1987 or newer).

Kit Includes:

• Two 3' Aluminum Duct Tubes
• One length of Flex tube (you cut to length for each side)
• Two AAF Backing plates (left & right)
• Eight hose clamps
• Attaching hardware
• AAF Adapter for the factory inlet.
