EE 531 Oil Filter

EE-531 Heavy-Duty Bypass Oil Filter (Replaces Hino 15607-2281)

Maximize the performance and lifespan of your heavy-duty diesel engines with the EE-531 Oil Filter. Specifically designed as a high-precision bypass filtration element, this filter works alongside your primary oil filter to capture ultra-fine contaminants, ensuring the purest possible lubrication for high-stress engine components.

The EE-531 is engineered to meet the stringent requirements of Hino 700 Series and Profia trucks, providing industrial-grade protection against engine wear and oil degradation.

Key Performance Features:

• Bypass Micro-Filtration: Specifically tuned to remove microscopic soot and metallic particles that standard full-flow filters may miss.

• Extended Service Intervals: By maintaining superior oil cleanliness, this filter helps extend the life of your engine oil and reduces maintenance downtime.

• Premium Media Construction: Uses multi-layered composite fiber paper designed for high heat resistance and maximum dirt-holding capacity.

• Industrial Durability: Features a reinforced internal structure to withstand the high-pressure environment of heavy-duty diesel lubrication systems.

Verified Compatibility & Cross-Reference

The EE-531 is a direct replacement for the Hino 15607-2281 and its high-performance variants.
