Features:

• 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 N54 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.
• 【Perfect Replacement】The OEM hose fitting is a known weak spot in the coolant system as it commonly cracks and leaks. Our upgraded water hose fitting is to replace the stock fitting with aluminum that will never wear out, crack or leak.
• 【Aircraft-grade 6061 Aluminum】Made of 6061 Billet Aluminum instead of plastic,which is durable and wear-resistant.
• 【Smooth Flow】There are no sharp corners on this fitting so that the coolant will not be disrupted as it passes through.
• 【Max Coolant Flow】Our aluminum fitting has a larger diameter than the OEM part which improves the coolant flow and cooling performance.
• 【Easy to Install】Direct fitment with no modification, easy installation.
