奇瑞西门子电喷喷油嘴 5WY2404A MIA11720 原厂规格替换

If your vehicle has idle instability, weak acceleration, or abnormal fuel consumption, or even cold-start difficulty with exhaust emitting black smoke, this usually indicates injectors aging clogging or poor atomization. In normal operation, the injector precisely controls fuel spray rate and atomization to ensure complete combustion and smooth power output. This is an OEM-spec replacement with OEM numbers 5WY2404A / MIA11720; fits Chery Siemens EFI systems (2000 onward). Installation requires cleaning fuel lines and replacing seals to avoid contaminants entering the system; after installation, ECU matching is required to ensure injector pulse width aligns with ECU data.
