Every detail counts in a Corvette restoration, and your windshield washer system is no exception. Without a functioning filter, debris can slip into the pump and clog the nozzles—leaving you without clear vision when you need it most. This reproduction filter and nut set restores the washer system to its proper function. Designed for 1975–1991 Corvette C3 and C4 models, it mounts directly into the passenger-side cowl location, just like the original. The filter safeguards fluid flow by keeping contaminants out, while the included nut locks the assembly securely in place. Whether you're completing a concours-level restoration or simply reviving a weekend driver, this GM reference # 22048299 component brings back both reliability and factory-correct detail to your Corvette's wiper system.
