Nissan March Sunny Primera Fuel Injector 16600-73C90 Factory Number Replacement

For Nissan March (Micra), Sunny, and Pulsar models, the injector(s) OEM 16600-73C90 (universal 1660073C90) are designed for standard pressure and voltage, directly replacing the original parts. They precisely control fuel spray to ensure proper mixture. If cold-start is difficult, exhaust emits black smoke, or power drops, the injector is aging or clogged. Replacing improves idle stability, reduces acceleration hesitation, and lowers fuel consumption with noticeably improved engine combustion efficiency.
