E9X N54/N55 Upper Radiator Hose Repair Kit

The factory upper radiator hose on N54/N55-powered BMWs is a known weak point, often cracking at the plastic quick-connect fitting and leaving you stranded. This billet aluminum upgrade kit eliminates that failure point by replacing the fragile OEM connector with a precision-machined, leak-proof alternative designed to last the life of the vehicle.

Made from 6061 aluminum, our fitting is CNC-machined to exact OEM dimensions and anodized for corrosion resistance. Paired with a high-temp 4-ply silicone hose, this kit offers improved reliability, flow, and heat resistance over stock, perfect for daily drivers, track builds, and high-boost setups.
