Our molded Corvette coolant heater hoses are made to OEM specifications to provide an easy direct installation and are manufactured in the USA with materials sourced from North America to provide quality.
This molded rubber hose attaches between the oil cooler pipe and the upper fitting on the oil cooler. Fits Corvettes with the Oil Cooler KC4 option.
For use on L98 Corvettes with the optional oil cooler (KC4). The KC4 option can be identified on the Corvette by where the oil filter screws into. If the oil filter screws into an oil cooler with an inlet and an outlet pipe which is then affixed to the engine block, you have the KC4 option. If the oil filter screws directly into the engine block, you do not have the KC4 option.
