Some of the biggest issues when owning a BMW can come from cooling system components. Even through years of improvement, the same failure is seen with the plastic fittings and adapters from years of hot to cold temperature fluctuation. The N52/N54/N55/N20 engine sees failure at the plastic cylinder head outlet adapter connecting the cylinder head to the thermostat hose. The stock plastic adapter simply shears off at the end of the barbed fitting, creating a massive coolant leak. The engineering team at ECS Tuning decided a billet aluminum piece was a much better option to contend with the temperature fluctuation. Since other offerings on the market want you to modify your OE hose to be reused, they 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 with type III anodized for exceptional durability and corrosion resistance. Much stronger part than OEM plastic Will not become brittle and fatigued over time due to thermal cycling. This will prevent the part from breaking during removal and re-installation. Follows OEM form for perfect fitment. Utilizes (and includes) OEM O-ring 11537545278 to ensure a proper seal. Recommended clamp size is 25-40mm

When it comes to cooling system hose replacement, the "U" shaped hose connecting the water pump to the thermostat is usually the first to fail. A lot of this comes from its close proximity to the hot downpipes, while some of this failure comes from the sharp bends in the hose.

Why not upgrade when you're due for a replacement? The ECS Tuning silicone hose replacement fixes these issue with two key features in their design. Offering this hose in a much more heat resistant silicone instead of OE rubber and having the hose wrapped in aluminum. The aluminum coating acts as a heat shield to further protect the silicone as well as reducing the temperatures forced on the coolant running through the hose.
