Product Overview
Hard starting, rough idle, uneven cylinder contribution, excess smoke or loss of power can point to injector trouble after compression, fuel supply and injection timing have been checked. Worn injectors can also cause poor atomization and uneven combustion.
These replacement injectors restore the metered fuel delivery and spray pattern the engine depends on for clean combustion. A multi-piece set is especially useful when several injectors have similar service hours or testing shows more than one injector is out of specification.
