Ford Motorcraft Fuel Injector, Ford (2004.5-10) 6.0L Power Stroke, Stock

These are genuine Ford Motorcraft Fuel Injectors from Ford. The Internal components of the Power Stroke Diesel fuel injectors are precisely engineered to the extreme tolerances that are so critical in the 6.0L Injector Assembly. Motorcraft Replaces the Entire Coil Assembly for each injector to prevent wire fatigue and poor cold-start conditions. Then, high pressure sealing surfaces inside the cylinder head assembly are refinished to original specifications (less than 2 microns of flatness). The precision flatness of these surfaces is critical to high pressure (20,000-plus psi), injection systems and assures long engine life, good mileage and performance. All Injectors have New Plungers installed in the intensifier bodies with precision-match honed to operate flawlessly at extreme pressures and temperatures with 100% durability and reliability. All Spool Valves are Replaced with New Parts, and both control valve bodies and spools are precision ground to Ford's exacting diametrical tolerance for excellent sealing and oil direction. Competitors re-use the old spool valve which is the main cause of hard starting issues Nozzle Assemblies are Inspected, then chemically treated and micro brushed to remove carbon and fuel residue. Each nozzle is then tested to ensure proper performance and emissions levels – the results: you needn't worry about high carbon buildup, nozzle coking, poor performance or emissions issues. Motorcraft offers New Rod Assemblies, new M4 screws and cone nuts, 100 percent flow-tested nozzles and nitrogen leak tested injector assemblies.
