Nissan Fuel Filter 16400-0W005 – Frontier (1998–2004), Pathfinder (1996–2004), Xterra; older 2.4L/3.3L/3.5L gasoline engines protects classic Nissan platforms with fine-micron media that traps rust, varnish, and tank debris. The low-restriction pathway maintains rail pressure for smoother idle and stronger pulls under load, while OE-accurate fittings provide a secure, leak-free install on high-mileage trucks and SUVs. Built with corrosion-resistant housings to handle winter salts and heat cycles, it’s ideal preventative maintenance for work and weekend rigs. Replace at schedule or when symptoms—hard starts, surging, hesitation—appear. Preserve pump life, regain throttle response, and keep trusted Nissan drivetrains running clean and confident.
