F2X/F3X B48 Upper Radiator Hose Repair Kit

The factory upper radiator hose on B48-powered BMWs is a known weak point, often cracking at the plastic quick-connect fittings and leaving you stranded. This billet aluminum upgrade kit eliminates that failure point by replacing the fragile OEM connectors with a precision-machined, leak-proof alternative designed to last the life of the vehicle. This kit has been revised for high production volume while retaining the same quality at a lower cost. Made from 6061 aluminum, our fittings are 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.
