Built from wear-resistant stainless steel with comfortable ABS handles, the kit targets hard-to-reach crevices in engines from Ford Powerstroke and Caterpillar to Navistar, MaxxForce, GM, Cummins, John Deere and Isuzu HPCR platforms.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this kit protect injector seats while removing deposits?\u003c\/h3\u003e\n\u003cp\u003eThe brushes are sized and shaped to clean deposits without overcutting or rounding the injector seat. One spiral tube brush scrubs the bore walls while the flat-bottom brush smooths and polishes the seat face for better sealing.
