EE 804 Air Filter

EE-804 High-Performance Air Filter (Replaces Hitachi 4286128)

The EE-804 Air Filter is a heavy-duty, radial-seal primary air element designed to provide maximum engine protection for high-performance excavators and commercial trucks. Engineered to replace the Hitachi 4286128, this filter ensures a clean air supply to your engine even in the most punishing, dust-heavy environments found on construction sites and off-road trails.

By utilizing high-density cellulose media and a precision-molded RadialSeal™, the EE-804 prevents dirt bypass and maintains consistent airflow, extending your engine's service life and optimizing fuel efficiency.

Key Performance Features:

• RadialSeal™ Technology: Creates a leak-proof, vibration-resistant seal to ensure no unfiltered air enters the engine.

• High Dirt-Holding Capacity: Multi-layered pleated media captures 99.9% of harmful particulates before they reach the intake.

• Reinforced Structure: Heavy-duty mesh inner and outer liners provide superior structural integrity under high-pressure intake.

• Direct OEM Fit: Built to the exact dimensions of the Hitachi original for a seamless, "drop-in" installation.

Verified Compatibility & Cross-Reference

The EE-804 is a widely used industrial and automotive air filter. It is verified to replace the following manufacturer part numbers:

Primary Vehicle & Equipment Applications

This filter is essential for a wide range of medium-to-heavy duty equipment, particularly those powered by Isuzu 4HK1 or 6HK1 engines:

• Hitachi Zaxis Excavators: ZX140W, ZX170W, ZX190W, ZX210, ZX240, and ZX270LC-3 series.

• Isuzu Trucks: F-Series (FTR34, FVR) and various N-Series trucks utilizing the 8-98071-421-0 filter.

• John Deere Machinery: 190DW and 220DW excavators.

• Case Excavators: CX130B, CX210B, and CX240B models.

• Kobelco Excavators: SK200 and SK210 series.

Technical Specifications

• Filter Type: Primary Radial Seal Air Filter

• Outer Diameter: 237mm (approx. 9.33")

• Inner Diameter: 131mm (approx. 5.15")

• Overall Height: 371mm (approx. 14.6")

Note: Many Hitachi and Isuzu systems use a secondary (inner) safety filter in tandem with this primary filter. The matching inner filter is typically the 4286130 (our part number EE-805). We recommend replacing both at the same time for maximum protection.
