Restore proper engine oil pressure with the genuine Motorcraft F4TZ-6674-A Oil Pressure Regulator Plunger. This OEM Ford component is a critical part of the oil pump pressure regulator assembly, working together with the regulator spring to maintain proper engine oil pressure throughout the RPM range.
Over time, the original regulator plunger can become worn, scored, or stick inside the oil pump housing. A sticking or damaged plunger may contribute to inconsistent oil pressure, delayed oil pressure build-up, or excessive pressure fluctuations. Replacing worn internal regulator components during an oil pump rebuild or engine overhaul helps restore factory oil pressure operation.
Motorcraft manufactures this component to Ford's original specifications for precise fitment, proper clearances, and long-term reliability.
