E9X N54/N55 Full Cooling Kit

The factory cooling hoses on N54/N55-powered BMWs are known to fail over time due to heat cycling, pressure, and brittle plastic connectors. This universal billet hose replacement kit replaces all major OEM plastic fittings and hoses with upgraded components engineered for long-term durability and performance.

Each fitting is CNC-machined from 6061-T6 aluminum to precise OEM dimensions and anodized for corrosion resistance. The included high-temp 4-ply silicone hoses are pressure-tested and designed to withstand extreme thermal and mechanical stress. Whether you daily drive, track, or push performance limits, this kit eliminates the most failure-prone areas in the N54/N55 cooling system.
