These aren't aftermarket knockoffs - these are the real OEM parts with part number 13500114, coming in original retail packaging just like you'd get from the dealership. The 4-pin design is super common in GM vehicles for controlling everything from fuel pumps and cooling fans to horn circuits and accessory power. Having three in the pack means you can replace what you need now and keep spares in your glove box for future issues - because relays always seem to fail at the worst possible times! The quality is exactly what you expect from GM OEM parts - proper materials, correct specifications, and reliable performance that aftermarket parts sometimes can't match. Installation is straightforward if you're comfortable with basic automotive electrical work, and having the right OEM part means no compatibility issues or error codes.
