This water spray nozzle kit can be fitted to your windshield washer reservoir/pump if you do not have a spray system installed, or used to add sprayers to your existing system. These nozzles can also be used to spray your intercooler, radiator, or anything else you need to keep cool. Can be used in conjunction with the Cusco Intercooler Spray Controller system or as a stand-alone manual system (when connected to windshield washer reservoir/pump).
