日产轩逸1.8L天籁2.0喷油嘴FBY2850，雾化高效喷射如新。

Nissan X-Trail/Altima/Sylphy 1.8L and Sentra 2.0 owners, note that the FBY2850 fuel injector directly affects atomization efficiency; OEM FBY2850 fits HR18 and other models. It precisely atomizes fuel and injects into the intake manifold for complete combustion, optimizing power output and fuel economy. Replacement difficulty moderate; labor 1.5–2 hours; thoroughly clean seals and fuel lines to prevent clogging. If you experience rough idle, sluggish acceleration, rising fuel consumption, or abnormal exhaust, this usually indicates injector atomization problems and requires replacement.
