4 x NGK Spark Plugs + Bosch Leads for Toyota 4 Runner RN130 Celica RA Corona RT

What is a spark plug and 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.
