Product Details
Part No. 55577403
Warranty Details (2 YR REPLACEMENT IF DEFECTIVE)
ACDelco GM Original Equipment Fuel Injectors are electro-magnetic valves that meter fuel into the engine's intake manifold or cylinders for combustion, and are GM-recommended replacements for your vehicle's original components. The engine control module (ECM) operates the injector by applying an electric current to the injector solenoid winding, causing the needle valve to open, and allowing pressurized fuel to be atomized into the intake airstream. These original equipment fuel injectors have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Product Features:
  • Atomizes fuel into the engine's intake manifold or cylinders, as part of the fuel and engine management system
  • Allows for a quick throttle response
  • Assists in cold engine starts
  • GM-recommended replacement part for your GM vehicle's original factory component
  • Offering the quality, reliability, and durability of GM OE
  • Manufactured to GM OE specification for fit, form, and function
