{"product_id":"e46-m3-brake-cooling-duct-kit","title":"E46 M3 Brake Cooling Duct Kit","description":"The Advanced Auto Fabrication E46 M3 Brake Cooling Duct Kit offers a significant upgrade for track-focused BMWs, specifically designed to combat brake fade and extend component life. This kit improves upon existing designs with ultra-high airflow inlets featuring a massive 4″ opening, manufactured from durable 3D-printed material. The included ABS plastic tubes are shaped for excellent airflow and a tight turning radius, allowing for up to 1.5 turns from straight even with large racing tires, while tapering to a 3″ flex hose for optimal performance and cost-efficiency.\n\nComplementing the ducting are specially designed backing plates. These feature an open-flow design to direct cool air into the brake hat and towards the wheel bearings, crucial for track conditions. By providing more air through the rotor veins and acting as a heat shield for shocks, ball joints, and tie rods, these powder-coated black backing plates help maintain consistent shock dampening, improve the longevity of steering and suspension components, and significantly increase wheel bearing life.\n\nThis kit is available in multiple configurations: Kit #1 includes inlets, molded tubes, flex hose, backing plates, and all necessary hardware for a complete installation. Kit #2 is for those who already possess AAF backing plates and need the ducting components. Kit #3 is designed for replacing damaged or broken ducting pieces, including only the inlets and molded tubes.\n\nImportant compatibility notes: This brake cooling duct kit is not for use with inner fenders or A\/C systems.","brand":"Advanced Auto Fabrication (AAF)","offers":[{"title":"Default Title","offer_id":52686805336376,"sku":"116102-116102.1-116102.2","price":300.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660672309.jpg?v=1784876926","url":"https:\/\/store.motormia.co\/products\/e46-m3-brake-cooling-duct-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
