The SP Tools Ford Power Stroke Injector Puller Kit, No. 16300, removes diesel injectors on 6.7L Power Stroke engines 2011 and newer. Over time and with many miles on the engine, the injectors become heavily coated with carbon between the tip and cylinder head, causing them to stick together, the company says. When using a factory tool to remove the injector, it can rock the injector and cause binding into the cylinder head, damaging the injector. This tool is designed to pull Ford injectors straight out without rocking, reducing the possibility of damaging the injector or cylinder head.
