Fuel Injector for Pontiac Sunfire 2.2L 2003-2005 and Chevrolet Cavalier 2.2L 2003-2005

These high impedance fuel injectors are made of durable metal and plastic material, designed to be used for a long time. They have been thoroughly tested to precisely match the internal coil resistance and fuel flow rate of the original equipment manufacturer (OEM) fuel injectors. This is a non-OEM product, intended as an accessory only.

The injectors come with pre-installed O-rings and feature a 4-hole disc orifice design. They operate at a voltage of DC 12V and are available in a black color. The replacement part numbers for these injectors are 12571863, 217-1561, FJ10573, 12574335, and 832-11211.

These fuel injectors are compatible with the following vehicles: Pontiac Sunfire 2.2L (2003-2005) and Chevrolet Cavalier 2.2L (2003-2005).

The installation process is as follows: 1. Ensure the engine is cool and disconnect the battery. 2. Remove the bolts and brackets from the fuel rail. 3. Disconnect the plug on each injector. 4. Lift the fuel rail and remove the existing injectors. 5. Press the new injectors into the fuel rail. Reattach the fuel rail and insert the injectors into their respective holes. 6. Bolt down the fuel rail, reattach the fuel line, and reconnect the injector connectors. Reconnect the battery. 7. Thoroughly check for fuel leaks before and after starting the engine.

The package includes 4 fuel injectors. These high-efficiency injectors are designed for fast cold-start performance, low fuel consumption, and improved engine performance. However, professional installation is highly recommended, as fuel injectors directly affect the air/fuel ratio, and new injectors may require a new or updated engine tune. It is also suggested to check the condition of other engine components before installation.
