BMW E81 / E82 / E87 / E88 1 Series, E90 / E91 / E92 / E93 3 Series & E84 X1 Silicone Coolant Expansion Tank Hose with Aluminum Flange (N52 / N52N / N51 Engines / Replaces 17127618510 / 17127565093)

For BMW E8X / E9X chassis, the engine coolant reservoir hose flange is extremely prone to breakage – both during repairs and in daily use. Once broken, it can lead to coolant leaks and high engine temperatures. This high-performance upgrade replaces the failure-prone factory plastic flange with 6061 aluminum alloy and replaces the factory rubber hose with triple-layer reinforced silicone for permanent durability.

Features:

• 6061 aluminum alloy flange – a durable solution to the problem of factory plastic flange breakage
• Triple-layer reinforced silicone hose – high pressure (3 bar) and high temperature resistant, with a special anti-aging formula to maintain long-term flexibility, no hardening, no cracking, avoiding the risk of sealing failure
• Upgraded hose clamps – the factory hose clamps are not suitable for reuse after long-term use
• Aesthetic enhancement – the customized silicone hose appearance is exquisite, eliminating the cheap feel of the factory parts
