EE 505 Air Filter

EE-505 High-Efficiency Air Filter

The EE-505 Air Filter is a heavy-duty filtration solution specifically engineered for high-performance diesel engines. It is a direct replacement for the 17801-3420P and is designed to provide maximum airflow while maintaining a 99% filtration efficiency rate against dust, soot, and silica.

Built with advanced synthetic or reinforced paper media, the EE-505 protects your engine's turbocharger and internal components from premature wear, especially in high-torque and commercial applications.

Key Features:

• Industrial Grade Filtration: Designed for heavy-duty trucks and large diesel engines.

• High Dust Holding Capacity: Extends service intervals even in harsh, dusty environments.

• Structural Integrity: Features a heavy-duty mesh or reinforced casing to prevent pleat collapse under high vacuum.

• Precision Seal: Polyurethane or rubber gaskets ensure a 100% airtight fit, preventing "leak-by."

Verified Cross-Reference & Interchange

The 17801-3420P (and its base number 17801-3420) is a specialized part number used primarily in the Hino and Toyota Heavy Duty ecosystems. Below are the verified interchanges for major brands:

Primary Vehicle Applications

This filter is most commonly found in medium and heavy-duty commercial vehicles. It is verified for use in:

• Hino Trucks: Specifically the Hino 500 Series and 700 Series (Models such as FM2P, RN8J, and SG series).

• Hino Buses: Various intercity and transit bus models.

• Toyota Dyna / Toyoace: Heavy-duty variants (check specific engine codes).

• Sisu Trucks: Certain European and specialty logistics models.

Verification Tip: Because part numbers in the 17801-series can vary slightly by region (e.g., -3420 vs -3420P), always confirm the filter's physical dimensions. The EE-505 typically measures approximately 390mm–400mm in height with an outer diameter of roughly 275mm–280mm.
