Key features

• 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 design that will never wear-out, crack or leak.
• Advanced Material and Design:Made of Billet 6061 Aluminum instead of plastic,which is durable and wear-resistant. There are no sharp corners on this fitting so that the coolant will not be disrupted as it passes through.
• Our aluminum fitting has a larger diameter than the OEM part which improves the coolant flow and cooling performance.
• Direct fitment with no modification,easy installation. Simply remove the end of the hose from the plastic fitting and then the fitting from the head (hose does not need to be removed from the thermostat housing to do this). Then install the replacement fitting to the head and slide the hose and hose clamp over the fitting.
