日产天籁阳光喷油嘴 16600-95F0A FBY21B0 燃油喷油器 高效雾化

When Nissan Teana or Sunny exhibits idle instability, acceleration hesitation, cold-start difficulty, or higher fuel consumption, typically the fuel injectors are aging or clogged causing poor fuel atomization. The injectors precisely atomize and inject fuel into cylinders to ensure proper air-fuel mixing, improving combustion efficiency and power response. Compatible with Nissan Teana (2013) and Sunny; OEM numbers 16600-95F0A, FBY21B0, FBY10F0. Before installation, thoroughly clean fuel path and replace seals; follow torque specs to avoid valve body deformation from over-tightening.
