This kit provides pilot cones, installers and a sizer to guide the seal onto the injector stem and compress it to the proper outside diameter before reinstallation into the cylinder head. It fits common 6mm and 7.5mm injector stems and covers many Ford ECO injectors plus a wide range of GM and Subaru direct-injection applications.\u003c\/p\u003e\n\n\u003ch3\u003eWhich engines and injector types does this kit work with?\u003c\/h3\u003e\n\u003cp\u003eThe Lisle 11-piece kit is designed for many modern direct-injection systems.

The pilot cone leads the seal onto the injector tip without twisting or nicking it. The installer pushes the seal down into position, and the sizer compresses the seal back to the needed outside diameter for cylinder-head installation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePilot cone: centers and starts the seal on the stem safely\u003c\/li\u003e\n  \u003cli\u003eInstaller: pushes the seal fully into the injector groove\u003c\/li\u003e\n  \u003cli\u003eSizer: compresses the seal to the correct OD for head installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the concrete benefits of using this specialized kit?\u003c\/h3\u003e\n\u003cp\u003eUsing the right tools reduces the chance of cutting or misplacing delicate Teflon seals, speeds up service time and helps ensure a leak-free reinstallation.
