Answer
What made you think those were bad and needed to be replaced? Have you checked the onboard codes? Have you checked the air and fuel filters? Have you tried to read the computer codes? It might be necessary to run a compression test and fuel pressure test. Try to isolate a problem before you rush in and replace parts.
It might even be good to hook up to an exhaust gas analyzer to figure out what's going on inside the engine. If it's high in oxides of nitrogen you might have a fuel delivery problem. If it's high in hydrocarbons you might have an ignition problem.
Investigate before replacing parts.
