Improved Racing's RFR-802 radiator hose is required for deleting the factory water-to-oil cooler in the the 2015 and later S550 Ford Mustang GT & GT 350.
The factory lower radiator hose on these vehicles features two tee connections for the water-to-oil cooler. These connections may be capped off instead, but this will result in a restriction to your coolant flow. We recommend replacing the hose with this one instead.
Does not include worm clamps.
Why Delete the Factory Water-to-Oil Cooler?
You may want to delete the factory oil cooler when upgrading to an air-to-oil cooler or when relocating the oil filter with a remote filter mount. There are two options for deleting the factory cooler. Both options first require the removal of the factory cooler (sandwiched between the oil filter and filter mount) and coolant lines, then replacing the lower radiator hose with RFR-802.
