The Genuine Porsche Fuel Injector Seal Kit - 471668 is a comprehensive kit designed to service the fuel injectors on a car. It includes four different products, each specifically chosen to ensure proper maintenance and functioning of the fuel injectors. The kit contains fuel injector seals, which are essential for preventing fuel leaks and maintaining proper pressure within the fuel system. It also includes o-rings, which provide a tight seal between the fuel injector and the engine, preventing any fuel from leaking out. The kit also includes gaskets, which help to create a tight seal between the fuel injector and the fuel rail. Finally, the kit contains washers, which are used to secure the fuel injector in place and prevent any movement or vibration. This kit is specifically designed for Porsche vehicles, but may also be compatible with other car models.
