Ford introduced the F-250 in 1953, when the automaker changed the names of the three full-size pickup trucks. In the 1997 model year, Ford introduced a new engine for the F-250 and F-350: the 6.8-liter V-10. The 6.8-liter-equipped 2004 Ford F-250 produced 310 horsepower and 425 pound-feet of torque. This engine used Ford’s famous coil-on-plug ignition system, which places a coil on top of each plug, generating reliable spark and minimal resistance. Ford recommends replacing the spark plugs on the 2004 Ford F-250 every 100,000 miles.

how to change spark plugs: ford v10 firing order

  1. Check the gap between the two electrodes on the 10 new Motorcraft AWSF-22E spark plugs (or equivalent), using a spark plug gap tool. The 6.8-liter engine requires a gap of 0.052 to 0.056 inches, so swap out the plugs with incorrect gaps for a new one. The recommended spark plugs for the 2004 F-250 are not adjustable.
  2. Follow the air inlet hose from the air filter box to the engine. Remove the two smaller hoses (idle air control supply and crankcase breather hoses) by pulling them out of the air inlet hose.
  3. Loosen the hose clamps on each end of the air intake hose, using a Phillips screwdriver, and pull the hose out of the engine compartment.
  4. Unplug the wire harness from the top of the coil pack by pressing the lock button and pulling the harness from the coil pack. Remove the bolts holding the coil pack to the motor, using a ratchet and socket, and pull the pack up, with a slight twisting motion, to remove it.
  5. Remove the spark plug, using a ratchet, a 6-inch extension, and a spark plug socket. Remove the old spark plug from the spark plug socket and insert the new plug into the socket.
  6. Hand tighten the new spark plug into the engine, using the spark plug socket and 6-inch extension. Apply 11 foot-pounds of torque to the spark plug with a torque wrench.
  7. Apply a thin layer of dielectric grease inside the rubber boot at the bottom of the coil pack and place the coil pack on the spark plug. Press the coil pack down toward the spark plug until it snaps into place.
  8. Reconnect the wire harness to the top of the coil pack and tighten the coil pack bolt to 4 to 5 foot-pounds, using a torque wrench and socket.
  9. Repeat steps 4 through 8 until you replace all 10 spark plugs.
  10. Reinstall the air inlet hose and tighten the hose clamps with a Phillips screwdriver. Reconnect the IAC and CCV hoses to their respective ports on the air inlet hose.
