The new AAF E30 Brake Duct Adapters are the perfect answer for your brake duct kit.
These brake duct adapters slide directly over the OEM e30 brake duct inlets. We suggest using a strong 2 part bonding adhesive to attach our brake duct adapter to the OEM brake duct inlet. This is ideal for maximum airflow, as it does not intrude into the air duct, and will create an air-tight seal around the joint. Since the AAF E30 Brake Duct Adapter is made from Polylactic Acid plastic, it bonds extraordinarily well with the OEM brake duct inlets.
The AAF E30 Brake Duct Adapter was designed using high-tech CAD software and 3D printed, making an ultra-strong lightweight part with a unique shape you can not get with any other manufacturing method.
