F-00E-200-419 Genuine Mopar® Fuel Injectors Set Of Six For Dodge Ram Cummins 6.7L

1. Deliver Fuel Accurately

• Supplies the exact amount of fuel the engine needs for current speed and load.

• Helps maintain optimal air-fuel ratio, usually around 14.7:1 for gasoline engines.

2. Atomize the Fuel

• Sprays fuel as a fine mist, not a stream.

• Fine mist mixes better with air, allowing complete combustion, which:

  • Produces more power

  • Reduces unburned fuel

  • Improves fuel efficiency

3. Control Timing

• Opens and closes in precise intervals controlled by the engine control unit (ECU).

• Ensures fuel enters exactly when the cylinder is ready to burn it.

4. Improve Engine Efficiency

• Proper fuel delivery means:

  • Better acceleration

  • Smooth idle

  • Lower fuel consumption

5. Reduce Emissions

• Complete combustion lowers:

  • Carbon monoxide (CO)

  • Hydrocarbons (HC)

  • Nitrogen oxides (NOx)

6. Enable Modern Engine Technologies

• Direct injection engines, turbocharging, and variable valve timing all rely on precise fuel injection for performance and efficiency.

1. Engine Misfires

• Cylinder misfires when the injector isn’t supplying enough fuel.

• Rough running at idle or under acceleration.

2. Poor Fuel Economy

• If the injector leaks or sprays too much fuel, the engine burns more fuel than necessary.

• Noticeable drop in miles per gallon (MPG).

3. Rough Idle

• Engine shakes or vibrates when stationary.

• Caused by uneven fuel delivery between cylinders.

4. Hard Starting

• Engine cranks but struggles to start.

• Often happens when injectors are clogged or not delivering fuel consistently.

5. Check Engine Light (CEL)

• Codes such as:

  • P0200–P0206 (Injector circuit issues)

  • P0300–P0306 (Cylinder misfire codes)

• CEL may blink if misfires are severe.

6. Fuel Odor

• Leaking injectors can cause strong fuel smell around the engine bay.

7. Black Smoke from Exhaust

• Too much fuel entering the combustion chamber produces rich mixture, causing black smoke.

8. Engine Knocking or Poor Performance

• Incorrect fuel spray pattern leads to incomplete combustion, which may cause knocking, hesitation, or lack of acceleration.

9. Contaminated Spark Plugs

• Spark plugs may show soot buildup or wet fuel deposits if injectors are leaking or clogged.
