OEM Fuel Injector for various Nissan and Infiniti models with the early style VQ35DE powertrain. 

Fuel injectors are critical components of the engine's fuel delivery system. They are responsible for spraying fuel into the combustion chamber in a precise and controlled manner. Over time, fuel injectors can become clogged, worn, or damaged, which can lead to various engine performance issues.

Here are some signs that a fuel injector may need to be replaced:

• Engine misfires or rough idle: A clogged or malfunctioning fuel injector may result in one or more cylinders not receiving the correct amount of fuel. This can cause engine misfires, a rough idle, or a noticeable loss of power
• Poor fuel efficiency: If a fuel injector is not functioning properly, it may not be delivering fuel efficiently, resulting in decreased fuel efficiency and increased fuel consumption.
• Engine hesitation or stumbling: A faulty fuel injector can cause hesitation or stumbling during acceleration, as it may not be supplying the necessary fuel to the engine in a consistent manner.
• Fuel odor or leaks: A damaged fuel injector can result in fuel leaks, which may cause a noticeable fuel odor around the engine or a visible presence of fuel under the vehicle.
• Check engine light: A malfunctioning fuel injector can trigger the engine's check engine light, indicating a problem in the fuel delivery system.
