EE 523 Air Filter

EE-523 Heavy-Duty Air Filter (Replaces 17801-2590)

The EE-523 Air Filter is a premium, high-capacity filtration solution designed for heavy-duty trucks and industrial vehicles. Engineered to replace the Hino 17801-2590, this filter ensures that your engine receives clean, debris-free air even in the most demanding environments like construction sites, long-haul trucking, and mining operations.

With a high-density pleated media design, the EE-523 maximizes surface area to trap fine dust and soot, protecting your cylinders from premature wear and maintaining your engine's fuel efficiency.

Key Performance Features:

• Heavy-Duty Filtration: Specifically designed for large-displacement diesel engines requiring high air intake volumes.

• Superior Seal Integrity: Features high-grade PU or metal end caps (depending on application) to ensure a 100% airtight fit, preventing "dust dusting."

• Structural Durability: Reinforced with a corrosion-resistant inner and outer metal mesh to prevent the filter media from collapsing under high pressure.

• Extended Service Life: High dirt-holding capacity reduces the frequency of replacements, lowering your total cost of ownership.

The EE-523 is a verified direct replacement for the Hino 17801-2590 and is compatible with several other major manufacturer part numbers.

Verification Note: Please note that while many Toyota filters use the "17801" prefix (e.g., for Corollas or Land Cruisers), the 17801-2590 is a specific Large Truck/Industrial filter. Always verify the dimensions (approx. 45cm height) to ensure this matches your heavy-duty application rather than a passenger car.
