What Are Fuel Injectors & Why They Matter
Fuel injectors are precision-engineered nozzles that deliver pressurized fuel into an engine’s intake air or combustion chamber at just the right time and rate. When they function correctly, they:
- Ensure optimal air–fuel mixture for power, efficiency, and emissions
- Enable smooth engine operation across varying speeds and loads
- Prevent misfire, rough idling, and fuel waste
Choosing a poor-quality injector or a mismatched size can lead to performance loss, engine damage, or excessive emissions.
