This kit combines a pilot cone to start the seal, an installer tool to push the seal onto the injector tip and a sizer to compress the seal to the right outer diameter before installation. It’s built for the common single- and double-sealed injectors found across a wide range of Ford, GM and Subaru applications, including many modern GM engines from 2010 onward.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this kit make seal replacement easier?\u003c\/h3\u003e\n\u003cp\u003eThe pilot cone centers and guides new seals onto the injector tip so you avoid tearing or misalignment.
