This product is made from high strength aerospace aluminum, Grade 6061 T6511.
Also, this product was designed to maximize the resistance to breakage, so that it will not fail as the OEM fitting does.
In addition to this, the coolant flow path through the center of the fitting is optimized to maximize coolant flow.
There are no sharp corners on this fitting so that the coolant will not be disrupted as it passes through.
this same line, the surface area of the coolant flow path is 23% larger

fitting from the head (hose does not need to be removed from the
thermostat housing to do this).
install the replacement aluminum fitting to the head and slide the hose
and hose clamp over the fitting. Fitting is machined from billet
aluminum 6061 T6511 (not cast, not forged).
