Generic pullers don't pull straight causing the injector to rock to one side. This could damage the head & injector beyond repair. The Schley 16400 injector puller is specially designed to mount to the cylinder head in the vehicle. The design pulls the injector straight reducing the chance of damaging the injector or head. The puller also removes the injector completely from the head, other competitor pullers fall short. Save time and money using this tool. Made from heat treated alloy steel for rigidity & durability.
