EE-524 Heavy-Duty Air Filter (Replaces Nissan 16546-99411)

Ensure your heavy-duty engine breathes clean, unrestricted air with the EE-524 Air Filter. Designed specifically for the high-demand environments of commercial trucking and industrial machinery, this premium air filter is a direct high-performance replacement for the Nissan 16546-99411.

By utilizing advanced filtration media, the EE-524 effectively captures microscopic dust and abrasive particles, preventing engine wear and maintaining optimal combustion for maximum fuel efficiency.

Key Performance Features:

• Industrial Grade Filtration: Multi-density media traps up to 99% of contaminants before they reach the engine.
