Some of the biggest issues when owning a BMW can come from cooling system components. Even through the years of improvement the same failure is seen with the plastic fittings and adapters from years of hot to cold temperature fluctuation. The N54 engine see failure at the plastic adapter connecting the thermostat hose to the cylinder head, this adapter simple 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 offering 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.
