Nissan Air Filter 16546-EA000 – Frontier and other trucks/SUVs (2005–2025 depending on engine) is built for tough duty, combining high capture efficiency with low restriction to sustain torque under load. OE-spec frames and gaskets create a secure, dust-tight seal that shields sensors and intake tracts from trail grit and job-site debris. Corrosion-resistant materials and moisture-stable media endure heat cycles, towing, and weather swings. The drop-in design supports fast service during oil changes. Replace per factory interval—or sooner after off-road or dusty conditions—to maintain fuel economy, throttle response, and dependable performance across hardworking Nissan pickups and SUVs.
