Changing spark plugs on Ford KA II

Replacement of the 4 spark plugs with 4 NGK brand spark plugs

I use a 1/2 ratchet with extension + a 16 mm long socket to unscrew 4 spark plugs

I use a 3/8 ratchet with extension + a 10 mm socket to unscrew the two air box mounting screws

Opening the engine hood

Locating the two air box mounting screws

Unscrew the two fixing screws

Disconnect the pipe that returns the oil vapor to the intake (breather)

The air box is held in place by a rubber pad on the back, you just have to pull it upwards to remove it.

We get a view of the ignition coil

The ignition harness

I proceed spark plug by spark plug, in order to avoid any errors in the ignition harness, I start with the driver's side cylinder.

Disconnect the harness at the coil and spark plug

We therefore have a view of the candle after removing the harness

Place the socket and the extension in order to loosen the first spark plug.

Compare your new spark plugs with your old ones

Replace the spark plug in its well. It is essential to do the first turns by hand, this will avoid damaging the thread!

Finish tightening with the torque wrench. The manufacturer recommends tightening to 21 NM.

Re-attach the ignition harness to the coil and spark plug then move on to the second cylinder

Disconnect the second beam

View of the second candle

Repeat the operation, loosening, tightening by hand then finishing with the torque wrench.

Do the same for cylinders 3 and 4, the procedure is identical as for the first cylinder

Replace the air box at the level of the throttle body and the rubber pad

Replace the breather

Then screw the two air box fixing screws back in.

Here is the change of spark plugs done!
