do88 BMW 135I / 335I N54 (E8X/E9X) Coolant Hose Set

The original coolant/radiator hoses on the N54 are manufactured in rubber, a material that, as these cars age, commonly cracks and fails over time. do88 developed this hose kit specifically to replace the OEM radiator and cooling system hoses with a genuinely more durable alternative, while also improving the look of the engine bay.

These hoses are entirely manufactured from high-quality silicone, reinforced with three to five layers of aramid fabric depending on the specific hose's inner diameter, allowing them to withstand high pressure and high temperatures for a long time. Available in either black or blue, there's no difference in performance between the two colours, it's purely a styling choice.

Please note: you'll need to reuse the original hose connections, and the original hose clamps must be cut off with a hacksaw during installation (a straightforward job, but worth knowing beforehand). do88 recommends purchasing their matching hose clamp kit (sold separately) at the same time, make sure the kit number matches the hose kit number.

Works with: Original hose connections (reused). Not compatible with vehicles fitted with an auxiliary parking heater.
