Genuine Spark Plugs x 4, What is a Spark Plug & what does it do? A spark plug operates by directing electrical current to flow through a centre electrode, forming a spark across an electrode (or air) gap, completing the circuit to a ground electrode.

The centre electrode is surrounded by a ceramic insulator which is non-conductive preventing current leakage and ensuring electricity flows in the desired direction. Vehicle compatibility information is provided as a guide only.

This listing has been made as accurate as possible using the latest information provided by FORD. There may be on occasions more than one compatible part for your vehicle.

If you are unsure please contact us with your vehicle registration and we will confirm the correct part required.
