Fuel injectors are little nozzles about the size of a lighter that squirt gas into the combustion chambers. You have one injector per cylinder, and they generally do not have to be replaced as a wear item unless they have failed. Some engines, like older VQ-series engines in early Nissan Maximas, are known to have higher injector failure rates than others.See Also:Rich Fuel MixtureAir FilterChokeAccelerator PumpMufflerCarburetor BowlTailpipeTDC
