Delphi Fuel Injector P/N:EX631042
Delphi EX631101 fuel injector for the 2011-2012 Ram 3500 6-cylinder 6.7L and other vehicles delivers fuel into the engine as a fine, controlled spray. The part is built to OE specifications for fit, form and function.
Hard cold starts, hesitation or a rough idle can be linked to an injector whose spray pattern has changed. A clogged fuel filter is another common cause, so these signs alone do not prove the injector is the problem.
