The New Holland P551100 is a premium spin-on engine oil filter, often cross-referenced to Donaldson P551100, engineered for robust performance and extended engine life in New Holland machinery. With an outer diameter of 93 mm, a length of 175 mm, and an M24 x 2 thread, this filter is designed for a precise fit. It features a 99% efficiency at 20 microns, effectively capturing contaminants, and includes both a bypass valve and an anti-drainback valve to ensure consistent oil flow and protection during cold starts. This filter is a direct replacement for several New Holland OEM part numbers, making it a reliable choice for maintaining optimal engine health in a wide range of New Holland agricultural and construction equipment.
