ECS Performance Coolant Outlet Hose Kit

Some of the biggest issues when owning a BMW can come from cooling system components. Even after many years of improvement, the same failure is seen with the plastic fittings and adapters from years of hot-to-cold temperature fluctuation. The N55 engine sees failure at the plastic adapter connecting the thermostat hose to the cylinder head; this adapter simply shears off at the end of the barbed fitting.

The engineering team here at ECS decided a billet aluminum piece was a much better option to contend with the temperature fluctuation, and since other offerings on the market want you to modify your OE hose to be reused, we even developed a silicone replacement hose. These 2 pieces can be purchased separately if you decide to reuse your existing OE hose or in a package kit together for a single click upgrade.

FEATURES

• Manufactured from billet 6061-T6 and type III anodized for exceptional durability and corrosion resistance.
  • Much stronger part than OEM plastic
  • Will not become brittle and fatigue over time due to thermal cycling. This will prevent the part from breaking during removal and reinstallation.
• Constructed of 4-ply reinforced silicone for improved durability over the failure-prone OE rubber hose.
• Fluorosilicone-lined internal layer for exceptional chemical resistance.
• Silicone offers reduced thermal conductivity as well as improved resistance to ozone and UV degradation for improved performance and durability.
• Follows the OEM form for perfect fitment.
• Utilizes OEM O-ring 11537545278 to ensure a proper seal.
